NAME
       exim - a	Mail Transfer Agent

SYNOPSIS
       exim [options] arguments	...
       mailq [options] arguments ...
       rsmtp [options] arguments ...
       rmail [options] arguments ...
       runq [options] arguments	...
       newaliases [options] arguments ...

DESCRIPTION

       Exim is a mail transfer agent (MTA) developed at	the University of Cam-
       bridge.	It is a	large program with very	many facilities.  For  a  full
       specification,  see the reference manual. This man page contains	only a
       description of the command line options.	It has been automatically gen-
       erated  from  the  reference  manual source, hopefully without too much
       mangling.

       Like other MTAs,	Exim replaces Sendmail,	and is normally	called by user
       agents  (MUAs)  using the path /usr/sbin/sendmail when they submit mes-
       sages for delivery (some	operating systems use /usr/lib/sendmail). This
       path  is	 normally set up as a symbolic link to the Exim	binary.	It may
       also be used by boot scripts to start the Exim daemon. Many  of	Exim's
       command line options are	compatible with	Sendmail so that it can	act as
       a drop-in replacement.

DEFAULT	ACTION

       If no options are present that  require	a  specific  action  (such  as
       starting	 the daemon or a queue runner, testing an address, receiving a
       message in a specific format, or	listing	the queue), and	there  are  no
       arguments  on  the command line,	Exim outputs a brief message about it-
       self and	exits.

       However,	if there is at least one command line argument,	-bm (accept  a
       local  message on the standard input, with the arguments	specifying the
       recipients) is assumed. Thus, for example,  if  Exim  is	 installed  in
       /usr/sbin, you can send a message from the command line like this:

	 /usr/sbin/exim	-i <recipient-address(es)>
	 <message content, including all the header lines>
	 CTRL-D

       The  -i	option	prevents a line	containing just	a dot from terminating
       the message. Only an end-of-file	(generated by typing CTRL-D if the in-
       put is from a terminal) does so.

SETTING	OPTIONS	BY PROGRAM NAME

       If  an Exim binary is called using one of the names listed in this sec-
       tion (typically via a symbolic link), certain options are assumed.

       mailq  Behave as	if the option -bp were present before  any  other  op-
	      tions.  The -bp option requests a	listing	of the contents	of the
	      mail queue on the	standard output.

       rsmtp  Behaves as if the	option -bS were	present	before any  other  op-
	      tions,  for compatibility	with Smail. The	-bS option is used for
	      reading in a number of messages in batched SMTP format.

       rmail  Behave as	if the -i and -oee options  were  present  before  any
	      other  options,  for compatibility with Smail. The name rmail is
	      used as an interface by some UUCP	systems. The -i	option	speci-
	      fies  that  a  dot  on  a	 line  by  itself does not terminate a
	      non-SMTP message;	-oee requests that errors detected in non-SMTP
	      messages be reported by emailing the sender.

       runq   Behave  as  if  the  option -q were present before any other op-
	      tions, for compatibility with Smail. The -q option causes	a sin-
	      gle  queue  runner process to be started.	It processes the queue
	      once, then exits.

       newaliases
	      Behave as	if the option -bi were present before  any  other  op-
	      tions,  for compatibility	with Sendmail. This option is used for
	      rebuilding Sendmail's alias file.	Exim does not have the concept
	      of a single alias	file, but can be configured to run a specified
	      command if called	with the -bi option.

OPTIONS

       --	 This is a pseudo-option whose only purpose  is	 to  terminate
		 the  options  and  therefore to cause subsequent command line
		 items to be treated as	arguments rather than options, even if
		 they begin with hyphens.

       --help	 This  option  causes  Exim  to	output a few sentences stating
		 what it is.  The same output is generated if the Exim	binary
		 is called with	no options and no arguments.

       --version This  option  is an alias for -bV and causes version informa-
		 tion to be displayed.

       -Ac	 -Am These options are used by Sendmail	for selecting configu-
		 ration	files and are ignored by Exim.

       -B<type>	 This  is  a Sendmail option for selecting 7 or	8 bit process-
		 ing. Exim is 8-bit clean; it ignores this option.

       -bd	 This option runs Exim as a  daemon,  awaiting	incoming  SMTP
		 connections.  Usually	the  -bd  option  is combined with the
		 -q<time> option, to specify that the daemon should also  ini-
		 tiate periodic	queue runs.

		 The  -bd  option can be used only by an admin user. If	either
		 of the	-d (debugging) or -v (verifying) options are set,  the
		 daemon	 does  not  disconnect	from the controlling terminal.
		 When running this way,	it can be stopped by pressing ctrl-C.

		 By default, Exim listens  for	incoming  connections  to  the
		 standard SMTP port on all the host's running interfaces. How-
		 ever, it is possible to listen	on other  ports,  on  multiple
		 ports,	and only on specific interfaces.

		 When  a  listening  daemon  is	started	without	the use	of -oX
		 (that is, without overriding the  normal  configuration),  it
		 writes	 its  process  id  to a	file called exim-daemon.pid in
		 Exim's	spool directory. This location can  be	overridden  by
		 setting  PID_FILE_PATH	in Local/Makefile. The file is written
		 while Exim is still running as	root.

		 When -oX is used on the command line  to  start  a  listening
		 daemon,  the process id is not	written	to the normal pid file
		 path. However,	-oP can	be used	to specify a path on the  com-
		 mand line if a	pid file is required.

		 The  SIGHUP signal can	be used	to cause the daemon to re-exe-
		 cute itself. This should be done whenever  Exim's  configura-
		 tion  file, or	any file that is incorporated into it by means
		 of the	.include facility, is changed, and also	whenever a new
		 version  of Exim is installed.	It is not necessary to do this
		 when other files that are referenced from  the	 configuration
		 (for  example,	 alias	files)	are changed, because these are
		 reread	each time they are used.

       -bdf	 This option has the same effect as -bd	except that  it	 never
		 disconnects  from  the	controlling terminal, even when	no de-
		 bugging is specified.

       -be	 Run Exim in expansion testing mode. Exim  discards  its  root
		 privilege,  to	prevent	ordinary users from using this mode to
		 read otherwise	inaccessible files. If no arguments are	given,
		 Exim  runs interactively, prompting for lines of data.	Other-
		 wise, it processes each argument in turn.

		 If Exim was built with	USE_READLINE=yes in Local/Makefile, it
		 tries	to  load  the libreadline library dynamically whenever
		 the -be option	is used	without	 command  line	arguments.  If
		 successful,  it  uses the readline() function,	which provides
		 extensive line-editing	facilities, for	reading	the test data.
		 A line	history	is supported.

		 Long expansion	expressions can	be split over several lines by
		 using backslash continuations.	As in Exim's runtime  configu-
		 ration, white space at	the start of continuation lines	is ig-
		 nored.	Each argument or  data	line  is  passed  through  the
		 string	 expansion  mechanism, and the result is output. Vari-
		 able values from the configuration file (for example,	$qual-
		 ify_domain)  are  available,  but  no message-specific	values
		 (such as $message_exim_id) are	set, because no	message	is be-
		 ing processed (but see	-bem and -Mset).

		 Note:	If  you	 use  this  mechanism to test lookups, and you
		 change	the data files or databases you	are  using,  you  must
		 exit  and  restart  Exim before trying	the same lookup	again.
		 Otherwise, because each Exim process caches  the  results  of
		 lookups, you will just	get the	same result as before.

		 Macro	processing  is	done on	lines before string-expansion:
		 new macros can	be defined and macros will be  expanded.   Be-
		 cause	macros	in the config file are often used for secrets,
		 those are only	available to admin users.

       -bem <filename>
		 This option operates like -be except that it must be followed
		 by the	name of	a file.	For example:

		   exim	-bem /tmp/testmessage

		 The file is read as a message (as if receiving	a locally-sub-
		 mitted	non-SMTP message) before any of	 the  test  expansions
		 are  done.  Thus,  message-specific  variables	 such as $mes-
		 sage_size and $header_from: are available.  However,  no  Re-
		 ceived:  header  is added to the message. If the -t option is
		 set, recipients are read from the headers in the normal  way,
		 and  are shown	in the $recipients variable. Note that recipi-
		 ents cannot be	given on the command line, because further ar-
		 guments are taken as strings to expand	(just like -be).

       -bF <filename>
		 This  option  is  the same as -bf except that it assumes that
		 the filter being tested is a system  filter.  The  additional
		 commands that are available only in system filters are	recog-
		 nized.

       -bf <filename>
		 This option runs Exim in user filter testing mode;  the  file
		 is  the  filter file to be tested, and	a test message must be
		 supplied on the standard input. If there are  no  message-de-
		 pendent tests in the filter, an empty file can	be supplied.

		 If  you want to test a	system filter file, use	-bF instead of
		 -bf. You can use both -bF and -bf on the same command,	in or-
		 der  to  test	a  system filter and a user filter in the same
		 run. For example:

		   exim	-bF /system/filter -bf /user/filter </test/message

		 This is helpful when the system filter	adds header  lines  or
		 sets filter variables that are	used by	the user filter.

		 If  the  test filter file does	not begin with one of the spe-
		 cial lines

		   # Exim filter
		   # Sieve filter

		 it is taken to	be a normal .forward file, and is  tested  for
		 validity under	that interpretation.

		 The  result of	an Exim	command	that uses -bf, provided	no er-
		 rors are detected, is a list of the actions that  Exim	 would
		 try  to take if presented with	the message for	real. More de-
		 tails of filter testing are given in  the  separate  document
		 entitled Exim's interfaces to mail filtering.

		 When testing a	filter file, the envelope sender can be	set by
		 the -f	option,	or by a	"From "	line at	the start of the  test
		 message. Various parameters that would	normally be taken from
		 the envelope recipient	address	of the message can be  set  by
		 means	of  additional command line options (see the next four
		 options).

       -bfd <domain>
		 This sets the domain of the recipient address when  a	filter
		 file  is being	tested by means	of the -bf option. The default
		 is the	value of $qualify_domain.

       -bfl <local part>
		 This sets the local part of the recipient address when	a fil-
		 ter  file is being tested by means of the -bf option. The de-
		 fault is the username of the process that calls Exim. A local
		 part  should be specified with	any prefix or suffix stripped,
		 because that is how it	appears	to the filter when  a  message
		 is actually being delivered.

       -bfp <prefix>
		 This  sets  the prefix	of the local part of the recipient ad-
		 dress when a filter file is being tested by means of the  -bf
		 option. The default is	an empty prefix.

       -bfs <suffix>
		 This  sets  the suffix	of the local part of the recipient ad-
		 dress when a filter file is being tested by means of the  -bf
		 option. The default is	an empty suffix.

       -bh <IP address>
		 This  option runs a fake SMTP session as if from the given IP
		 address, using	the standard input and output. The IP  address
		 may  include a	port number at the end,	after a	full stop. For
		 example:

		   exim	-bh 10.9.8.7.1234
		   exim	-bh fe80::a00:20ff:fe86:a061.5678

		 When an IPv6 address is given,	it is converted	into canonical
		 form.	In  the	case of	the second example above, the value of
		 $sender_host_address after conversion to the  canonical  form
		 is fe80:0000:0000:0a00:20ff:fe86:a061.5678.

		 Comments  as  to what is going	on are written to the standard
		 error file. These include lines beginning with	"LOG" for any-
		 thing that would have been logged.  This facility is provided
		 for testing configuration options for incoming	 messages,  to
		 make  sure  they  implement the required policy. For example,
		 you can test your relay controls using	-bh.

		 Warning 1: You	can test features of  the  configuration  that
		 rely  on  ident  (RFC 1413) information by using the -oMt op-
		 tion. However,	Exim cannot actually perform an	ident  callout
		 when testing using -bh	because	there is no incoming SMTP con-
		 nection.

		 Warning 2: Address verification  callouts  are	 also  skipped
		 when  testing using -bh. If you want these callouts to	occur,
		 use -bhc instead.

		 Messages supplied during the testing session  are  discarded,
		 and  nothing  is  written to any of the real log files. There
		 may be	pauses when DNS	(and other) lookups are	taking	place,
		 and of	course these may time out. The -oMi option can be used
		 to specify a specific IP interface and	port if	this is	impor-
		 tant, and -oMaa and -oMai can be used to set parameters as if
		 the SMTP session were authenticated.

		 The exim_checkaccess utility is a "packaged" version  of  -bh
		 whose	output	just  states whether a given recipient address
		 from a	given host is acceptable or not.

		 Features such as authentication  and  encryption,  where  the
		 client	 input is not plain text, cannot easily	be tested with
		 -bh. Instead, you should use a	specialized SMTP test  program
		 such as swaks.

       -bhc <IP	address>
		 This  option operates in the same way as -bh, except that ad-
		 dress verification callouts are performed if  required.  This
		 includes consulting and updating the callout cache database.

       -bi	 Sendmail  interprets  the  -bi	option as a request to rebuild
		 its alias file.  Exim does not	have the concept of  a	single
		 alias	file,  and so it cannot	mimic this behaviour. However,
		 calls to /usr/lib/sendmail with the -bi option	tend to	appear
		 in various scripts such as NIS	make files, so the option must
		 be recognized.

		 If -bi	is encountered,	the command specified by  the  bi_com-
		 mand  configuration  option  is run, under the	uid and	gid of
		 the caller of Exim. If	the -oA	option is used,	its  value  is
		 passed	 to  the  command  as an argument.  The	command	set by
		 bi_command may	not contain arguments. The command can use the
		 exim_dbmbuild	utility, or some other means, to rebuild alias
		 files if this is required. If the bi_command  option  is  not
		 set, calling Exim with	-bi is a no-op.

       -bI:help	 We  shall  provide various options starting -bI: for querying
		 Exim for information.	The output of many of  these  will  be
		 intended  for	machine	 consumption.	This  one is not.  The
		 -bI:help option asks Exim for a synopsis of supported options
		 beginning -bI:.  Use of any of	these options shall cause Exim
		 to exit after producing the requested output.

       -bI:dscp	 This option causes Exim to emit an alphabetically sorted list
		 of all	recognised DSCP	names.

       -bI:sieve This option causes Exim to emit an alphabetically sorted list
		 of all	supported Sieve	protocol extensions on stdout, one per
		 line.	 This is anticipated to	be useful for ManageSieve (RFC
		 5804) implementations,	in providing that protocol's SIEVE ca-
		 pability  response line.  As the precise list may depend upon
		 compile-time build options, which this	option will adapt  to,
		 this is the only way to guarantee a correct response.

       -bm	 This  option  runs  an	Exim receiving process that accepts an
		 incoming, locally-generated message on	 the  standard	input.
		 The  recipients  are  given  as the command arguments (except
		 when -t is also present - see below). Each argument can be  a
		 comma-separated  list	of RFC 2822 addresses. This is the de-
		 fault option for selecting the	 overall  action  of  an  Exim
		 call;	it  is	assumed	 if  no	 other	conflicting  option is
		 present.

		 If any	addresses in the message are unqualified (have no  do-
		 main),	they are qualified by the values of the	qualify_domain
		 or qualify_recipient options, as appropriate. The -bnq	option
		 (see  below)  provides	 a way of suppressing this for special
		 cases.

		 Policy	checks on the contents of local	messages  can  be  en-
		 forced	by means of the	non-SMTP ACL.

		 The  return  code  is zero if the message is successfully ac-
		 cepted. Otherwise, the	action is controlled by	the  -oex  op-
		 tion setting -	see below.

		 The format of the message must	be as defined in RFC 2822, ex-
		 cept that, for	compatibility with Sendmail and	Smail, a  line
		 in one	of the forms

		   From	sender Fri Jan	5 12:55	GMT 1997
		   From	sender Fri, 5 Jan 97 12:55:01

		 (with the weekday optional, and possibly with additional text
		 after the date) is permitted to appear	at the	start  of  the
		 message.  There  appears to be	no authoritative specification
		 of the	format of this line. Exim recognizes  it  by  matching
		 against  the regular expression defined by the	uucp_from_pat-
		 tern option, which can	be changed if necessary.

		 The specified sender is treated as if it were	given  as  the
		 argument  to  the  -f	option,	 but  if  a  -f	option is also
		 present, its argument is used in preference  to  the  address
		 taken	from the message. The caller of	Exim must be a trusted
		 user for the sender of	a message to be	set in this way.

       -bmalware <filename>
		 This debugging	option causes Exim to scan the given  file  or
		 directory  (depending	on  the	used scanner interface), using
		 the malware scanning framework.  The option of	av_scanner in-
		 fluences  this	 option, so if av_scanner's value is dependent
		 upon an expansion then	the  expansion	should	have  defaults
		 which	apply to this invocation.  ACLs	are not	invoked, so if
		 av_scanner references an ACL variable then that variable will
		 never be populated and	-bmalware will fail.

		 Exim will have	changed	working	directory before resolving the
		 filename, so using fully qualified  pathnames	is  advisable.
		 Exim  will  be	running	as the Exim user when it tries to open
		 the file, rather than as the invoking user.  This option  re-
		 quires	admin privileges.

		 The  -bmalware	 option	will not be extended to	be more	gener-
		 ally useful, there are	better tools for file-scanning.	  This
		 option	exists to help administrators verify their Exim	and AV
		 scanner configuration.

       -bnq	 By default,  Exim  automatically  qualifies  unqualified  ad-
		 dresses  (those without domains) that appear in messages that
		 are submitted locally (that is, not over TCP/IP). This	quali-
		 fication  applies  both  to  addresses	 in envelopes, and ad-
		 dresses in header lines. Sender addresses are qualified using
		 qualify_domain, and recipient addresses using qualify_recipi-
		 ent (which defaults to	the value of qualify_domain).

		 Sometimes, qualification is not wanted. For example,  if  -bS
		 (batch	 SMTP) is being	used to	re-submit messages that	origi-
		 nally came from remote	 hosts	after  content	scanning,  you
		 probably  do  not  want  to  qualify unqualified addresses in
		 header	lines. (Such lines will	be present only	 if  you  have
		 not enabled a header syntax check in the appropriate ACL.)

		 The  -bnq  option suppresses all qualification	of unqualified
		 addresses in messages that originate on the local host.  When
		 this  is  used, unqualified addresses in the envelope provoke
		 errors	(causing message rejection) and	unqualified  addresses
		 in header lines are left alone.

       -bP	 If this option	is given with no arguments, it causes the val-
		 ues of	all Exim's main	configuration options to be written to
		 the  standard	output.	The values of one or more specific op-
		 tions can be requested	by giving their	 names	as  arguments,
		 for example:

		   exim	-bP qualify_domain hold_domains

		 However,  any	option	setting	 that  is preceded by the word
		 "hide"	in the configuration file is not shown in full,	except
		 to  an	 admin user. For other users, the output is as in this
		 example:

		   mysql_servers = <value not displayable>

		 If config is given as an argument, the	config is  output,  as
		 it  was  parsed,  any	include	file resolved, any comment re-
		 moved.

		 If config_file	is given as an argument, the name of the  run-
		 time configuration file is output. (configure_file works too,
		 for backward compatibility.)	If  a  list  of	 configuration
		 files was supplied, the value that is output here is the name
		 of the	file that was actually used.

		 If the	-n flag	is given, then for most	modes of -bP operation
		 the name will not be output.

		 If log_file_path or pid_file_path are given, the names	of the
		 directories where log files and daemon	pid files are  written
		 are  output,  respectively.  If  these	 values	are unset, log
		 files are written in a	sub-directory of the  spool  directory
		 called	 log,  and  the	 pid file is written directly into the
		 spool directory.

		 If -bP	is followed by a name preceded by +, for example,

		   exim	-bP +local_domains

		 it searches for a matching named list of  any	type  (domain,
		 host, address,	or local part) and outputs what	it finds.

		 If  one  of  the words	router,	transport, or authenticator is
		 given,	followed by the	name  of  an  appropriate  driver  in-
		 stance,  the  option settings for that	driver are output. For
		 example:

		   exim	-bP transport local_delivery

		 The generic driver options are	output first, followed by  the
		 driver's private options. A list of the names of drivers of a
		 particular type can be	obtained by using  one	of  the	 words
		 router_list,  transport_list,	or  authenticator_list,	 and a
		 complete list of all drivers with their option	 settings  can
		 be obtained by	using routers, transports, or authenticators.

		 If  environment  is given as an argument, the set of environ-
		 ment variables	is output, line	by line.  Using	 the  -n  flag
		 suppresses the	value of the variables.

		 If  invoked  by  an  admin  user,  then macro,	macro_list and
		 macros	are available,	similarly  to  the  drivers.   Because
		 macros	 are sometimes used for	storing	passwords, this	option
		 is restricted.	 The output format is one item per line.   For
		 the  "-bP  macro  <name>" form, if no such macro is found the
		 exit status will be nonzero.

       -bp	 This option requests a	listing	of the contents	 of  the  mail
		 queue	on  the	standard output. If the	-bp option is followed
		 by a list of message ids, just	those messages are listed.  By
		 default,  this	option can be used only	by an admin user. How-
		 ever, the queue_list_requires_admin option can	be  set	 false
		 to allow any user to see the queue.

		 Each  message	in  the	queue is displayed as in the following
		 example:

		   25m	2.9K 0t5C6f-0000c8-00 <alice@wonderland.fict.example>
			     red.king@looking-glass.fict.example
			     <other addresses>

		 The first line	contains the length of time  the  message  has
		 been  in the queue (in	this case 25 minutes), the size	of the
		 message (2.9K), the unique local identifier for the  message,
		 and  the  message  sender,  as	contained in the envelope. For
		 bounce	messages, the sender address is	empty, and appears  as
		 "<>".	If  the	 message was submitted locally by an untrusted
		 user who overrode the default sender address, the user's  lo-
		 gin name is shown in parentheses before the sender address.

		 If  the  message  is  frozen (attempts	to deliver it are sus-
		 pended) then the text "*** frozen ***"	is  displayed  at  the
		 end of	this line.

		 The  recipients  of the message (taken	from the envelope, not
		 the headers) are displayed on	subsequent  lines.  Those  ad-
		 dresses  to  which the	message	has already been delivered are
		 marked	with the letter	D. If an  original  address  gets  ex-
		 panded	 into  several addresses via an	alias or forward file,
		 the original is displayed with	a D only when  deliveries  for
		 all of	its child addresses are	complete.

       -bpa	 This  option  operates	like -bp, but in addition it shows de-
		 livered addresses that	were generated from the	 original  top
		 level	address(es) in each message by alias or	forwarding op-
		 erations. These addresses are flagged with  "+D"  instead  of
		 just "D".

       -bpc	 This  option  counts the number of messages in	the queue, and
		 writes	the total to the standard output. It is	restricted  to
		 admin users, unless queue_list_requires_admin is set false.

       -bpr	 This  option  operates	like -bp, but the output is not	sorted
		 into chronological order of message arrival. This  can	 speed
		 it  up	 when  there are lots of messages in the queue,	and is
		 particularly useful if	the output is going  to	 be  post-pro-
		 cessed	in a way that doesn't need the sorting.

       -bpra	 This option is	a combination of -bpr and -bpa.

       -bpru	 This option is	a combination of -bpr and -bpu.

       -bpu	 This  option  operates	 like  -bp  but	shows only undelivered
		 top-level addresses for  each	message	 displayed.  Addresses
		 generated by aliasing or forwarding are not shown, unless the
		 message was deferred after processing by a  router  with  the
		 one_time option set.

       -brt	 This  option  is for testing retry rules, and it must be fol-
		 lowed by up to	three arguments. It causes Exim	to look	for  a
		 retry	rule  that  matches  the values	and to write it	to the
		 standard output. For example:

		   exim	-brt bach.comp.mus.example
		   Retry rule: *.comp.mus.example  F,2h,15m; F,4d,30m;

		  The first argument, which is required, can be	a complete ad-
		 dress	in the form local_part@domain, or it can be just a do-
		 main name. If the second argument contains a dot, it  is  in-
		 terpreted as an optional second domain	name; if no retry rule
		 is found for the first	argument, the second  is  tried.  This
		 ties  in  with	 Exim's	behaviour when looking for retry rules
		 for remote hosts - if no rule is found	that matches the host,
		 one that matches the mail domain is sought. Finally, an argu-
		 ment that is the name of a specific delivery error,  as  used
		 in setting up retry rules, can	be given. For example:

		   exim	-brt haydn.comp.mus.example quota_3d
		   Retry rule: *@haydn.comp.mus.example	quota_3d  F,1h,15m

       -brw	 This  option  is  for testing address rewriting rules,	and it
		 must be followed by a single argument,	consisting of either a
		 local	part  without  a  domain, or a complete	address	with a
		 fully qualified domain. Exim outputs how this	address	 would
		 be rewritten for each possible	place it might appear.

       -bS	 This  option  is used for batched SMTP	input, which is	an al-
		 ternative interface for non-interactive local message submis-
		 sion.	A number of messages can be submitted in a single run.
		 However, despite its name, this is  not  really  SMTP	input.
		 Exim  reads each message's envelope from SMTP commands	on the
		 standard input, but generates no responses. If	the caller  is
		 trusted,  or  untrusted_set_sender is set, the	senders	in the
		 SMTP MAIL commands are	believed; otherwise the	sender is  al-
		 ways the caller of Exim.

		 The  message  itself is read from the standard	input, in SMTP
		 format	(leading dots doubled),	terminated by a	line  contain-
		 ing  just a single dot. An error is provoked if the terminat-
		 ing dot is missing. A further message may then	follow.

		 As for	other local message submissions, the contents  of  in-
		 coming	 batch SMTP messages can be checked using the non-SMTP
		 ACL.  Unqualified addresses are automatically qualified using
		 qualify_domain	 and qualify_recipient,	as appropriate,	unless
		 the -bnq option is used.

		 Some other SMTP commands are recognized in  the  input.  HELO
		 and EHLO act as RSET; VRFY, EXPN, ETRN, and HELP act as NOOP;
		 QUIT quits, ignoring the rest of the standard input.

		 If any	error is encountered, reports are written to the stan-
		 dard output and error streams,	and Exim gives up immediately.
		 The return code is 0 if no error was detected;	it is 1	if one
		 or more messages were accepted	before the error was detected;
		 otherwise it is 2.

       -bs	 This option causes Exim to accept one	or  more  messages  by
		 reading  SMTP	commands  on the standard input, and producing
		 SMTP replies on the standard output. SMTP policy controls, as
		 defined  in  ACLs are applied.	 Some user agents use this in-
		 terface as a way of passing locally-generated messages	to the
		 MTA.

		 In  this  usage,  if  the  caller  of Exim is trusted,	or un-
		 trusted_set_sender is set, the	senders	of messages are	 taken
		 from  the SMTP	MAIL commands.	Otherwise the content of these
		 commands is ignored and the sender is set up as  the  calling
		 user. Unqualified addresses are automatically qualified using
		 qualify_domain	and qualify_recipient, as appropriate,	unless
		 the -bnq option is used.

		 The -bs option	is also	used to	run Exim from inetd, as	an al-
		 ternative to using a listening	daemon.	Exim  can  distinguish
		 the  two  cases  by  checking whether the standard input is a
		 TCP/IP	socket.	When Exim is called from inetd,	the source  of
		 the mail is assumed to	be remote, and the comments above con-
		 cerning senders and qualification do not apply. In this situ-
		 ation,	 Exim  behaves in exactly the same way as it does when
		 receiving a message via the listening daemon.

       -bt	 This option runs Exim in address testing mode,	in which  each
		 argument is taken as a	recipient address to be	tested for de-
		 liverability. The results are written to the standard output.
		 If  a test fails, and the caller is not an admin user,	no de-
		 tails of the failure are output, because these	might  contain
		 sensitive  information	 such  as  usernames and passwords for
		 database lookups.

		 If no arguments are given, Exim runs in an  interactive  man-
		 ner, prompting	with a right angle bracket for addresses to be
		 tested.

		 Unlike	the -be	test option, you cannot	arrange	 for  Exim  to
		 use  the  readline()  function, because it is running as root
		 and there are security	issues.

		 Each address is handled as if it were the  recipient  address
		 of  a	message	 (compare the -bv option). It is passed	to the
		 routers and the result	is written  to	the  standard  output.
		 However, any router that has no_address_test set is bypassed.
		 This can make -bt easier to use for genuine routing tests  if
		 your first router passes everything to	a scanner program.

		 The  return code is 2 if any address failed outright; it is 1
		 if no address failed outright but at least one	could  not  be
		 resolved  for	some  reason. Return code 0 is given only when
		 all addresses succeed.

		 Note: When actually delivering	a message, Exim	removes	dupli-
		 cate  recipient  addresses after routing is complete, so that
		 only one delivery takes place.	 This  does  not  happen  when
		 testing  with	-bt;  the  full	 results of routing are	always
		 shown.

		 Warning: -bt can only do relatively simple testing. If	any of
		 the  routers  in  the	configuration  makes  any tests	on the
		 sender	address	of a message, you can use the -f option	to set
		 an appropriate	sender when running -bt	tests. Without it, the
		 sender	is assumed to be the calling user at the default qual-
		 ifying	 domain.  However,  if	you  have set up (for example)
		 routers whose behaviour depends on the	contents of an	incom-
		 ing  message, you cannot test those conditions	using -bt. The
		 -N option provides a possible way of doing such tests.

       -bV	 This option causes Exim to write the current version  number,
		 compilation  number,  and compilation date of the exim	binary
		 to the	standard output.  It also lists	the DBM	 library  that
		 is  being used, the optional modules (such as specific	lookup
		 types), the drivers that are included in the binary, and  the
		 name of the runtime configuration file	that is	in use.

		 As  part of its operation, -bV	causes Exim to read and	syntax
		 check its configuration file. However,	this is	a static check
		 only. It cannot check values that are to be expanded. For ex-
		 ample,	although a misspelt ACL	verb is	detected, an error  in
		 the  verb's arguments is not. You cannot rely on -bV alone to
		 discover (for example)	all the	typos  in  the	configuration;
		 some realistic	testing	is needed. The -bh and -N options pro-
		 vide more dynamic testing facilities.

       -bv	 This option runs Exim in address verification mode, in	 which
		 each  argument	is taken as a recipient	address	to be verified
		 by the	routers. (This does not	involve	any verification call-
		 outs).	 During	 normal	operation, verification	happens	mostly
		 as a consequence processing a verify condition	in an ACL.  If
		 you  want to test an entire ACL, possibly including callouts,
		 see the -bh and -bhc options.

		 If verification fails,	and the	caller is not an  admin	 user,
		 no  details  of  the  failure are output, because these might
		 contain sensitive information such as usernames and passwords
		 for database lookups.

		 If  no	 arguments are given, Exim runs	in an interactive man-
		 ner, prompting	with a right angle bracket for addresses to be
		 verified.

		 Unlike	 the  -be  test	option,	you cannot arrange for Exim to
		 use the readline() function, because it is  running  as  exim
		 and there are security	issues.

		 Verification differs from address testing (the	-bt option) in
		 that routers that have	no_verify set are skipped, and if  the
		 address  is  accepted	by  a router that has fail_verify set,
		 verification fails. The address is verified as	a recipient if
		 -bv  is used; to test verification for	a sender address, -bvs
		 should	be used.

		 If the	-v option is not set, the output consists of a	single
		 line  for  each  address,  stating whether it was verified or
		 not, and giving a reason in the latter	case. Without -v, gen-
		 erating more than one address by redirection causes verifica-
		 tion to end successfully, without considering	the  generated
		 addresses.  However,  if  just	one address is generated, pro-
		 cessing continues, and	the generated address must verify suc-
		 cessfully for the overall verification	to succeed.

		 When -v is set, more details are given	of how the address has
		 been handled, and in the case of address redirection, all the
		 generated  addresses  are  also  considered. Verification may
		 succeed for some and fail for others.

		 The return code is 2 if any address failed outright; it is  1
		 if  no	 address failed	outright but at	least one could	not be
		 resolved for some reason. Return code 0 is  given  only  when
		 all addresses succeed.

		 If any	of the routers in the configuration makes any tests on
		 the sender address of a message, you should use the -f	option
		 to  set an appropriate	sender when running -bv	tests. Without
		 it, the sender	is assumed to be the calling user at  the  de-
		 fault qualifying domain.

       -bvs	 This  option  acts  like  -bv,	 but verifies the address as a
		 sender	rather than a  recipient  address.  This  affects  any
		 rewriting and qualification that might	happen.

       -bw	 This  option  runs  Exim  as a	daemon,	awaiting incoming SMTP
		 connections, similarly	to the -bd option.  All	port  specifi-
		 cations on the	command-line and in the	configuration file are
		 ignored.  Queue-running may not be specified.

		 In this mode, Exim expects to be passed  a  socket  as	 fd  0
		 (stdin) which is listening for	connections.  This permits the
		 system	to start up and	have inetd (or equivalent)  listen  on
		 the  SMTP  ports,  starting an	Exim daemon for	each port only
		 when the first	connection is received.

		 If the	option is given	as -bw<time> then the time is a	 time-
		 out, after which the daemon will exit,	which should cause in-
		 etd to	listen once more.

       -C <filelist>
		 This option causes Exim to  find  the	runtime	 configuration
		 file  from  the given list instead of from the	list specified
		 by the	CONFIGURE_FILE compile-time setting. Usually, the list
		 will  consist	of  just  a  single  filename, but it can be a
		 colon-separated list of names.	In this	case, the  first  file
		 that  exists  is used.	Failure	to open	an existing file stops
		 Exim from proceeding any further along	the list, and an error
		 is generated.

		 When this option is used by a caller other than root, and the
		 list is different from	the compiled-in	list,  Exim  gives  up
		 its  root  privilege  immediately, and	runs with the real and
		 effective uid and gid set to those of the  caller.   However,
		 if  a	TRUSTED_CONFIG_LIST file is defined in Local/Makefile,
		 that file contains a list of full pathnames,  one  per	 line,
		 for  configuration files which	are trusted. Root privilege is
		 retained for any configuration	file so	listed,	as long	as the
		 caller	is the Exim user (or the user specified	in the CONFIG-
		 URE_OWNER option, if any), and	as long	as  the	 configuration
		 file is not writeable by inappropriate	users or groups.

		 Leaving  TRUSTED_CONFIG_LIST  unset precludes the possibility
		 of testing a configuration using -C right through message re-
		 ception  and delivery,	even if	the caller is root. The	recep-
		 tion works, but by that time, Exim is	running	 as  the  Exim
		 user,	so when	it re-executes to regain privilege for the de-
		 livery, the use of -C causes privilege	to be  lost.  However,
		 root  can test	reception and delivery using two separate com-
		 mands (one to put a message in	the queue, using -odq, and an-
		 other to do the delivery, using -M).

		 If  ALT_CONFIG_PREFIX is defined in Local/Makefile, it	speci-
		 fies a	prefix string with which any file named	in a  -C  com-
		 mand  line  option must start.	In addition, the filename must
		 not contain the sequence /../.	 However, if the value of  the
		 -C  option is identical to the	value of CONFIGURE_FILE	in Lo-
		 cal/Makefile, Exim ignores -C and proceeds as usual. There is
		 no  default  setting for ALT_CONFIG_PREFIX; when it is	unset,
		 any filename can be used with -C.

		 ALT_CONFIG_PREFIX can be used to confine alternative configu-
		 ration	 files	to  a directory	to which only root has access.
		 This prevents someone who has broken into  the	 Exim  account
		 from  running	a privileged Exim with an arbitrary configura-
		 tion file.

		 The -C	facility is useful  for	 ensuring  that	 configuration
		 files	are syntactically correct, but cannot be used for test
		 deliveries, unless the	caller is privileged, or unless	it  is
		 an  exotic  configuration that	does not require privilege. No
		 check is made on the owner or group of	the files specified by
		 this option.

       -D<macro>=<value>
		 This  option can be used to override macro definitions	in the
		 configuration file. However, like -C, if it is	used by	an un-
		 privileged  caller, it	causes Exim to give up its root	privi-
		 lege.	If DISABLE_D_OPTION is defined in Local/Makefile,  the
		 use of	-D is completely disabled, and its use causes an imme-
		 diate error exit.

		 If WHITELIST_D_MACROS is defined in  Local/Makefile  then  it
		 should	 be a colon-separated list of macros which are consid-
		 ered safe and,	if -D only supplies macros from	this list, and
		 the  values  are  acceptable, then Exim will not give up root
		 privilege if the caller is root, the Exim run-time  user,  or
		 the  CONFIGURE_OWNER, if set.	This is	a transition mechanism
		 and is	expected to be removed in the future.  Acceptable val-
		 ues for the macros satisfy the	regexp:	^[A-Za-z0-9_/.-]*$

		 The entire option (including equals sign if present) must all
		 be within one command line item. -D can be used  to  set  the
		 value	of  a  macro  to  the  empty string, in	which case the
		 equals	sign is	optional. These	two commands are synonymous:

		   exim	-DABC  ...
		   exim	-DABC= ...

		 To include spaces in a	macro definition item, quotes must  be
		 used.	If  you	 use  quotes,  spaces are permitted around the
		 macro name and	the equals sign. For example:

		   exim	'-D ABC	= something' ...

		 -D may	be repeated up to 10 times on a	 command  line.	  Only
		 macro names up	to 22 letters long can be set.

       -d<debug	options>
		 This option causes debugging information to be	written	to the
		 standard error	stream.	It is restricted to  admin  users  be-
		 cause debugging output	may show database queries that contain
		 password information. Also,  the  details  of	users'	filter
		 files	should be protected. If	a non-admin user uses -d, Exim
		 writes	an error message to the	standard error stream and  ex-
		 its with a non-zero return code.

		 When  -d is used, -v is assumed. If -d	is given on its	own, a
		 lot of	standard debugging data	is output.  This  can  be  re-
		 duced,	or increased to	include	some more rarely needed	infor-
		 mation, by directly following -d with a  string  made	up  of
		 names	preceded by plus or minus characters. These add	or re-
		 move sets  of	debugging  data,  respectively.	 For  example,
		 -d+filter  adds  filter  debugging, whereas -d-all+filter se-
		 lects only filter debugging. Note that	no spaces are  allowed
		 in the	debug setting. The available debugging categories are:

		   acl		   ACL interpretation
		   auth		   authenticators
		   deliver	   general delivery logic
		   dns		   DNS lookups (see also resolver)
		   dnsbl	   DNS black list (aka RBL) code
		   exec		   arguments for execv() calls
		   expand	   detailed debugging for string expansions
		   filter	   filter handling
		   hints_lookup	   hints data lookups
		   host_lookup	   all types of	name-to-IP address handling
		   ident	   ident lookup
		   interface	   lists of local interfaces
		   lists	   matching things in lists
		   load		   system load checks
		   local_scan	   can be used by local_scan()
		   lookup	   general lookup code and all lookups
		   memory	   memory handling
		   noutf8	   modifier: avoid UTF-8 line-drawing
		   pid		   modifier: add pid to	debug output lines
		   process_info	   setting info	for the	process	log
		   queue_run	   queue runs
		   receive	   general message reception logic
		   resolver	   turn	on the DNS resolver's debugging	output
		   retry	   retry handling
		   rewrite	   address rewriting
		   route	   address routing
		   timestamp	    modifier:  add  timestamp  to debug	output
		 lines
		   tls		   TLS logic
		   transport	   transports
		   uid		   changes of uid/gid and looking up uid/gid
		   verify	   address verification	logic
		   all		   almost all of the above  (see  below),  and
		 also -v

		 The  all  option  excludes  memory when used as +all, but in-
		 cludes	it for -all. The reason	for this is that +all is some-
		 thing	that  people  tend to use when generating debug	output
		 for Exim maintainers. If +memory is included, an awful	lot of
		 output	 that  is  very	rarely of interest is generated, so it
		 now has to be explicitly requested. However, -all  does  turn
		 everything off.

		 The  resolver option produces output only if the DNS resolver
		 was compiled with DEBUG enabled. This is not the case in some
		 operating systems. Also, unfortunately, debugging output from
		 the DNS resolver is written to	stdout rather than stderr.

		 The default (-d with no argument) omits expand,  filter,  in-
		 terface,  load,  memory,  pid,	resolver, and timestamp.  How-
		 ever, the pid selector	is forced when debugging is turned  on
		 for  a	daemon,	which then passes it on	to any re-executed Ex-
		 ims. Exim also	automatically adds the pid to debug lines when
		 several remote	deliveries are run in parallel.

		 The timestamp selector	causes the current time	to be inserted
		 at the	start of all debug output lines. This  can  be	useful
		 when trying to	track down delays in processing.

		 The  noutf8  selector	disables the use of UTF-8 line-drawing
		 characters to	group  related	information.   When  disabled.
		 ascii-art  is	used  instead.	Using the +all option does not
		 set this modifier,

		 If the	debug_print option is set in any driver,  it  produces
		 output	whenever any debugging is selected, or if -v is	used.

       -dd<debug options>
		 This  option  behaves	exactly	 like -d except	when used on a
		 command that starts a daemon process. In that case, debugging
		 is  turned  off for the subprocesses that the daemon creates.
		 Thus, it is useful for	monitoring the behaviour of the	daemon
		 without creating as much output as full debugging does.

       -dropcr	 This  is  an  obsolete	option that is now a no-op. It used to
		 affect	the way	Exim handled CR	and LF characters in  incoming
		 messages.

       -E	 This  option  specifies  that	an  incoming  message is a lo-
		 cally-generated delivery failure report. It  is  used	inter-
		 nally	by Exim	when handling delivery failures	and is not in-
		 tended	for external use. Its only effect is to	stop Exim gen-
		 erating certain messages to the postmaster, as	otherwise mes-
		 sage cascades could occur in some situations. As part of  the
		 same option, a	message	id may follow the characters -E. If it
		 does, the log entry for the receipt of	the new	 message  con-
		 tains the id, following "R=", as a cross-reference.

       -ex	 There	are  a	number	of  Sendmail options starting with -oe
		 which seem to be called by various programs without the lead-
		 ing  o	 in the	option.	For example, the vacation program uses
		 -eq. Exim treats all options of the form  -ex	as  synonymous
		 with the corresponding	-oex options.

       -F <string>
		 This  option  sets  the sender's full name for	use when a lo-
		 cally-generated message is being accepted. In the absence  of
		 this option, the user's gecos entry from the password data is
		 used. As users	are generally permitted	to alter  their	 gecos
		 entries, no security considerations are involved. White space
		 between -F and	the <string> is	optional.

       -f <address>
		 This option sets the address of the envelope sender of	a  lo-
		 cally-generated  message (also	known as the return path). The
		 option	can normally be	used only by a trusted user,  but  un-
		 trusted_set_sender can	be set to allow	untrusted users	to use
		 it.

		 Processes running  as	root  or  the  Exim  user  are	always
		 trusted. Other	trusted	users are defined by the trusted_users
		 or trusted_groups options. In the absence of -f,  or  if  the
		 caller	 is  not trusted, the sender of	a local	message	is set
		 to the	caller's login name at the default qualify domain.

		 There is one exception	to the restriction on the use  of  -f:
		 an empty sender can be	specified by any user, trusted or not,
		 to create a message that can never provoke a bounce. An empty
		 sender	 can  be  specified either as an empty string, or as a
		 pair of angle brackets	with nothing between them, as in these
		 examples of shell commands:

		   exim	-f '<>'	user@domain
		   exim	-f "" user@domain

		 In  addition,	the use	of -f is not restricted	when testing a
		 filter	file with -bf or when testing or  verifying  addresses
		 using the -bt or -bv options.

		 Allowing  untrusted  users  to	change the sender address does
		 not of	itself make it possible	to send	anonymous  mail.  Exim
		 still	checks that the	From: header refers to the local user,
		 and if	it does	not, it	adds a Sender: header, though this can
		 be overridden by setting no_local_from_check.

		 White	space  between	-f and the <address> is	optional (that
		 is, they can be given as two arguments	or one combined	 argu-
		 ment).	 The sender of a locally-generated message can also be
		 set (when permitted) by an initial "From " line in  the  mes-
		 sage  -  see the description of -bm above - but if -f is also
		 present, it overrides "From ".

       -G	 This option is	equivalent to an ACL applying:

		   control = suppress_local_fixups

		 for every message received.  Note that	Sendmail will complain
		 about	such bad formatting, where Exim	silently just does not
		 fix it	up.  This may change in	future.

		 As this affects audit	information,  the  caller  must	 be  a
		 trusted user to use this option.

       -h <number>
		 This  option is accepted for compatibility with Sendmail, but
		 has no	effect.	(In Sendmail it	overrides the "hop count"  ob-
		 tained	by counting Received: headers.)

       -i	 This option, which has	the same effect	as -oi,	specifies that
		 a dot on a line by itself should not terminate	 an  incoming,
		 non-SMTP message. I can find no documentation for this	option
		 in Solaris 2.4	Sendmail, but the mailx	command	in Solaris 2.4
		 uses it. See also -ti.

       -L <tag>	 This  option  is  equivalent to setting syslog_processname in
		 the config file and setting log_file_path to syslog.  Its use
		 is  restricted	to administrators.  The	configuration file has
		 to be read and	parsed,	to  determine  access  rights,	before
		 this is set and takes effect, so early	configuration file er-
		 rors will not honour this flag.

		 The tag should	not be longer than 32 characters.

       -M <message id> <message	id> ...
		 This option requests Exim to run a delivery attempt  on  each
		 message  in turn. If any of the messages are frozen, they are
		 automatically thawed before the delivery  attempt.  The  set-
		 tings	of queue_domains, queue_smtp_domains, and hold_domains
		 are ignored.

		 Retry hints for any of	the addresses are  overridden  -  Exim
		 tries	to  deliver  even if the normal	retry time has not yet
		 been reached. This option requires the	caller to be an	 admin
		 user.	However, there is an option called prod_requires_admin
		 which can be set false	to relax this  restriction  (and  also
		 the same requirement for the -q, -R, and -S options).

		 The  deliveries  happen  synchronously, that is, the original
		 Exim process does not terminate until all  the	 delivery  at-
		 tempts	have finished. No output is produced unless there is a
		 serious error.	If you want to see what	is happening, use  the
		 -v option as well, or inspect Exim's main log.

       -Mar <message id> <address> <address> ...
		 This option requests Exim to add the addresses	to the list of
		 recipients of the message ("ar" for  "add  recipients").  The
		 first	argument  must be a message id,	and the	remaining ones
		 must be email addresses. However, if the  message  is	active
		 (in  the  middle  of  a delivery attempt), it is not altered.
		 This option can be used only by an admin user.

       -MC <transport> <hostname> <host	IP> <sequence number> <message id>
		 This option is	not intended for use by	external  callers.  It
		 is  used internally by	Exim to	invoke another instance	of it-
		 self to deliver a waiting message using an existing SMTP con-
		 nection,  which is passed as the standard input. This must be
		 the final option, and the caller must be  root	 or  the  Exim
		 user in order to use it.

       -MCA	 This  option  is not intended for use by external callers. It
		 is used internally by Exim in conjunction with	 the  -MC  op-
		 tion. It signifies that the connection	to the remote host has
		 been authenticated.

       -MCD	 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion. It signifies that the remote host  supports  the	 ESMTP
		 DSN extension.

       -MCd	 This  option  is not intended for use by external callers. It
		 is used internally by Exim in conjunction with	the -d	option
		 to  pass  on  an  information	string	on  the	purpose	of the
		 process.

       -MCG <queue name>
		 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion. It signifies that an alternate queue is used, named  by
		 the following argument.

       -MCK	 This  option  is not intended for use by external callers. It
		 is used internally by Exim in conjunction with	 the  -MC  op-
		 tion.	It  signifies  that  a	remote host supports the ESMTP
		 CHUNKING extension.

       -MCP	 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion. It signifies that the server to which Exim is connected
		 supports pipelining.

       -MCQ <process id> <pipe fd>
		 This  option  is not intended for use by external callers. It
		 is used internally by Exim in conjunction with	the -MC	option
		 when  the original delivery was started by a queue runner. It
		 passes	on the process id of the queue runner,	together  with
		 the  file  descriptor	number of an open pipe.	Closure	of the
		 pipe signals the final	completion of  the  sequence  of  pro-
		 cesses	 that  are passing messages through the	same SMTP con-
		 nection.

       -MCS	 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion, and passes on the  fact	that  the  ESMTP  SIZE	option
		 should	 be  used on messages delivered	down the existing con-
		 nection.

       -MCT	 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion, and passes on the fact that the host to which  Exim  is
		 connected supports TLS	encryption.

       -MCr <SNI>
		 -MCs <SNI> These options are not intended for use by external
		 callers. It is	used internally	by Exim	 in  conjunction  with
		 the  -MCt  option,  and  passes on the	fact that a TLS	Server
		 Name Indication was sent as part of  the  channel  establish-
		 ment.	 The  argument	gives the SNI string.  The "r" variant
		 indicates a DANE-verified connection.

       -MCt <IP	address> <port>	<cipher>
		 This option is	not intended for use by	external  callers.  It
		 is  used  internally  by Exim in conjunction with the -MC op-
		 tion, and passes on the fact that  the	 connection  is	 being
		 proxied by a parent process for handling TLS encryption.  The
		 arguments give	the local address and port being proxied,  and
		 the TLS cipher.

       -Mc <message id>	<message id> ...
		 This  option  requests	Exim to	run a delivery attempt on each
		 message, in turn, but unlike the -M option, it	does check for
		 retry	hints, and respects any	that are found.	This option is
		 not very useful to external callers. It  is  provided	mainly
		 for internal use by Exim when it needs	to re-invoke itself in
		 order to regain root privilege	for a delivery.	 However,  -Mc
		 can  be  useful when testing, in order	to run a delivery that
		 respects retry	times and other	options	such  as  hold_domains
		 that are overridden when -M is	used. Such a delivery does not
		 count as a queue run.	If you want to run a specific delivery
		 as if in a queue run, you should use -q with a	message	id ar-
		 gument. A distinction between queue run deliveries and	 other
		 deliveries is made in one or two places.

       -Mes <message id> <address>
		 This option requests Exim to change the sender	address	in the
		 message to the	given address, which must be a fully qualified
		 address  or  "<>" ("es" for "edit sender"). There must	be ex-
		 actly two arguments. The first	argument must be a message id,
		 and  the second one an	email address. However,	if the message
		 is active (in the middle of a delivery	attempt),  its	status
		 is  not  altered.   This  option can be used only by an admin
		 user.

       -Mf <message id>	<message id> ...
		 This option requests Exim to  mark  each  listed  message  as
		 "frozen".  This  prevents  any	delivery attempts taking place
		 until the message is "thawed",	either manually	or as a	result
		 of  the  auto_thaw  configuration option.  However, if	any of
		 the messages are active (in the  middle  of  a	 delivery  at-
		 tempt),  their	status is not altered. This option can be used
		 only by an admin user.

       -Mg <message id>	<message id> ...
		 This option requests Exim to give up trying  to  deliver  the
		 listed	 messages,  including any that are frozen. However, if
		 any of	the messages are active, their status is not  altered.
		 For  non-bounce messages, a delivery error message is sent to
		 the sender, containing	the text "cancelled by administrator".
		 Bounce	 messages  are just discarded. This option can be used
		 only by an admin user.

       -MG <queue name>	<message id> <message id> ...
		 This option requests that each	listed message be  moved  from
		 its  current queue to the given named queue.  The destination
		 queue name argument is	required, but can be an	 empty	string
		 to  define  the  default queue.  If the messages are not cur-
		 rently	located	in the default queue, a	-qG<name> option  will
		 be required to	define the source queue.

       -Mmad <message id> <message id> ...
		 This option requests Exim to mark all the recipient addresses
		 in the	messages as already delivered ("mad" for "mark all de-
		 livered").  However,  if any message is active	(in the	middle
		 of a delivery attempt), its status is not altered.  This  op-
		 tion can be used only by an admin user.

       -Mmd <message id> <address> <address> ...
		 This  option requests Exim to mark the	given addresses	as al-
		 ready delivered ("md" for "mark delivered"). The first	 argu-
		 ment  must  be	 a  message id,	and the	remaining ones must be
		 email addresses. These	are matched to recipient addresses  in
		 the message in	a case-sensitive manner. If the	message	is ac-
		 tive (in the middle of	a delivery attempt), its status	is not
		 altered. This option can be used only by an admin user.

       -Mrm <message id> <message id> ...
		 This  option  requests	Exim to	remove the given messages from
		 the queue. No bounce messages are sent; each message is  sim-
		 ply  forgotten.  However,  if any of the messages are active,
		 their status is not altered. This option can be used only  by
		 an  admin  user or by the user	who originally caused the mes-
		 sage to be placed in the queue.

       -Mset <message id>
		 This option is	useful only in conjunction with	-be (that  is,
		 when testing string expansions). Exim loads the given message
		 from its spool	before doing the test expansions, thus setting
		 message-specific  variables  such  as	$message_size  and the
		 header	variables. The $recipients variable is made available.
		 This feature is provided to make it easier to test expansions
		 that make use of these	variables. However, this option	can be
		 used only by an admin user. See also -bem.

       -Mt <message id>	<message id> ...
		 This  option  requests	 Exim to "thaw"	any of the listed mes-
		 sages that are	"frozen", so that delivery  attempts  can  re-
		 sume.	However, if any	of the messages	are active, their sta-
		 tus is	not altered. This option can be	used only by an	 admin
		 user.

       -Mvb <message id>
		 This  option  causes  the  contents  of the message body (-D)
		 spool file to be written to the standard output. This	option
		 can be	used only by an	admin user.

       -Mvc <message id>
		 This  option  causes  a  copy of the complete message (header
		 lines plus body) to be	written	to the standard	output in  RFC
		 2822 format. This option can be used only by an admin user.

       -Mvh <message id>
		 This  option  causes the contents of the message headers (-H)
		 spool file to be written to the standard output. This	option
		 can be	used only by an	admin user.

       -Mvl <message id>
		 This option causes the	contents of the	message	log spool file
		 to be written to the standard output. This option can be used
		 only by an admin user.

       -m	 This  is  apparently  a  synonym  for -om that	is accepted by
		 Sendmail, so Exim treats it that way too.

       -N	 This is a debugging option that inhibits delivery of  a  mes-
		 sage at the transport level. It implies -v. Exim goes through
		 many of the motions of	delivery - it  just  doesn't  actually
		 transport  the	message, but instead behaves as	if it had suc-
		 cessfully done	so. However, it	does not make any  updates  to
		 the  retry  database,	and the	log entries for	deliveries are
		 flagged with "*>" rather than "=>".

		 Because -N discards any message to  which  it	applies,  only
		 root  or the Exim user	are allowed to use it with -bd,	-q, -R
		 or -M.	In other words,	an ordinary user can use it only  when
		 supplying  an	incoming  message  to which it will apply. Al-
		 though	transportation never fails when	-N is set, an  address
		 may  be  deferred  because  of	 a  configuration problem on a
		 transport, or a routing problem. Once -N has been used	for  a
		 delivery  attempt,  it	 sticks	to the message,	and applies to
		 any subsequent	delivery attempts that	may  happen  for  that
		 message.

       -n	 This option is	interpreted by Sendmail	to mean	"no aliasing".
		 For normal modes of operation,	it is ignored by  Exim.	  When
		 combined  with	-bP it makes the output	more terse (suppresses
		 option	names, environment values and config pretty printing).

       -O <data> This option is	interpreted by Sendmail	to mean	set option. It
		 is ignored by Exim.

       -oA <file name>
		 This  option  is  used	by Sendmail in conjunction with	-bi to
		 specify an alternative	alias filename.	Exim handles -bi  dif-
		 ferently; see the description above.

       -oB <n>	 This is a debugging option which limits the maximum number of
		 messages that can be  delivered  down	one  SMTP  connection,
		 overriding  the  value	 set  in any smtp transport. If	<n> is
		 omitted, the limit is set to 1.

       -odb	 This option applies to	all modes in which Exim	accepts	incom-
		 ing  messages,	 including  the	 listening daemon. It requests
		 "background" delivery of such messages, which means that  the
		 accepting process automatically starts	a delivery process for
		 each message received,	but does not  wait  for	 the  delivery
		 processes to finish.

		 When  all  the	 messages  have	 been  received, the reception
		 process exits,	leaving	the delivery processes	to  finish  in
		 their	own  time.  The	 standard output and error streams are
		 closed	at the start of	each delivery process.	 This  is  the
		 default action	if none	of the -od options are present.

		 If  one  of  the  queueing  options in	the configuration file
		 (queue_only or	queue_only_file, for example)  is  in  effect,
		 -odb  overrides  it if	queue_only_override is set true, which
		 is the	default	setting. If queue_only_override	is set	false,
		 -odb has no effect.

       -odf	 This option requests "foreground" (synchronous) delivery when
		 Exim has accepted a locally-generated message.	(For the  dae-
		 mon  it  is  exactly the same as -odb.) A delivery process is
		 automatically started to deliver the message, and Exim	 waits
		 for it	to complete before proceeding.

		 The original Exim reception process does not finish until the
		 delivery process for the final	message	has ended.  The	 stan-
		 dard error stream is left open	during deliveries.

		 However,   like   -odb,   this	  option   has	no  effect  if
		 queue_only_override is	false and one of the queueing  options
		 in the	configuration file is in effect.

		 If  there is a	temporary delivery error during	foreground de-
		 livery, the message is	left in	the queue for later  delivery,
		 and the original reception process exits.

       -odi	 This  option is synonymous with -odf. It is provided for com-
		 patibility with Sendmail.

       -odq	 This option applies to	all modes in which Exim	accepts	incom-
		 ing  messages,	 including  the	listening daemon. It specifies
		 that the accepting process should not automatically  start  a
		 delivery  process  for	 each  message	received. Messages are
		 placed	in the queue, and  remain  there  until	 a  subsequent
		 queue	runner process encounters them.	There are several con-
		 figuration options (such as queue_only) that can be  used  to
		 queue incoming	messages under certain conditions. This	option
		 overrides all of them and also	-odqs. It always forces	queue-
		 ing.

       -odqs	 This option is	a hybrid between -odb/-odi and -odq.  However,
		 like  -odb  and  -odi,	 this  option	has   no   effect   if
		 queue_only_override  is false and one of the queueing options
		 in the	configuration file is in effect.

		 When -odqs does operate, a delivery process  is  started  for
		 each  incoming	 message, in the background by default,	but in
		 the foreground	if -odi	is also	 present.  The	recipient  ad-
		 dresses are routed, and local deliveries are done in the nor-
		 mal way. However, if any SMTP deliveries are  required,  they
		 are  not  done	 at  this  time, so the	message	remains	in the
		 queue until a subsequent queue	runner process encounters  it.
		 Because routing was done, Exim	knows which messages are wait-
		 ing for which hosts, and so a number of messages for the same
		 host	can   be   sent	 in  a	single	SMTP  connection.  The
		 queue_smtp_domains configuration option has the  same	effect
		 for specific domains. See also	the -qq	option.

       -oee	 If an error is	detected while a non-SMTP message is being re-
		 ceived	(for example, a	malformed address), the	error  is  re-
		 ported	to the sender in a mail	message.

		 Provided  this	 error	message	is successfully	sent, the Exim
		 receiving process exits with a	return code of zero.  If  not,
		 the return code is 2 if the problem is	that the original mes-
		 sage has no recipients, or 1 for any other  error.   This  is
		 the default -oex option if Exim is called as rmail.

       -oem	 This  is the same as -oee, except that	Exim always exits with
		 a non-zero return code, whether or not	the error message  was
		 successfully  sent.   This is the default -oex	option,	unless
		 Exim is called	as rmail.

       -oep	 If an error is	detected while a non-SMTP message is being re-
		 ceived,  the  error  is  reported by writing a	message	to the
		 standard error	file (stderr).	The return code	is 1  for  all
		 errors.

       -oeq	 This option is	supported for compatibility with Sendmail, but
		 has the same effect as	-oep.

       -oew	 This option is	supported for compatibility with Sendmail, but
		 has the same effect as	-oem.

       -oi	 This  option, which has the same effect as -i,	specifies that
		 a dot on a line by itself should not terminate	 an  incoming,
		 non-SMTP  message.  Otherwise,	 a  single dot does terminate,
		 though	Exim does no special processing	for other  lines  that
		 start	with  a	 dot. This option is set by default if Exim is
		 called	as rmail. See also -ti.

       -oitrue	 This option is	treated	as synonymous with -oi.

       -oMa <host address>
		 A number of options starting with -oM can be used to set val-
		 ues  associated  with	remote hosts on	locally-submitted mes-
		 sages (that is, messages not received over TCP/IP). These op-
		 tions	can be used by any caller in conjunction with the -bh,
		 -be, -bf, -bF,	-bt, or	-bv testing options. In	other  circum-
		 stances, they are ignored unless the caller is	trusted.

		 The  -oMa  option  sets the sender host address. This may in-
		 clude a port number at	the end, after a full  stop  (period).
		 For example:

		   exim	-bs -oMa 10.9.8.7.1234

		 An  alternative syntax	is to enclose the IP address in	square
		 brackets, followed by a colon and the port number:

		   exim	-bs -oMa [10.9.8.7]:1234

		 The IP	address	is placed in  the  $sender_host_address	 vari-
		 able, and the port, if	present, in $sender_host_port. If both
		 -oMa and -bh are present on the command line, the sender host
		 IP address is taken from whichever one	is last.

       -oMaa <name>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMaa option sets  the	 value	of  $sender_host_authenticated
		 (the  authenticator  name).  This option can be used with -bh
		 and -bs to set	up an authenticated SMTP session without actu-
		 ally using the	SMTP AUTH command.

       -oMai <string>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMai option sets the value of	$authenticated_id (the id that
		 was  authenticated).	This  overrides	the default value (the
		 caller's login	id, except with	-bh, where  there  is  no  de-
		 fault)	for messages from local	sources.

       -oMas <address>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMas option sets the authenticated sender value in  $authen-
		 ticated_sender.  It overrides the sender address that is cre-
		 ated from the caller's	 login	id  for	 messages  from	 local
		 sources,  except  when	-bh is used, when there	is no default.
		 For both -bh and -bs, an authenticated	sender that is	speci-
		 fied on a MAIL	command	overrides this value.

       -oMi <interface address>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMi option sets the IP interface address value. A port  num-
		 ber  may  be included,	using the same syntax as for -oMa. The
		 interface address is placed in	$received_ip_address  and  the
		 port number, if present, in $received_port.

       -oMm <message reference>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMm option sets the message reference, e.g. message-id,  and
		 is  logged  during delivery. This is useful when some kind of
		 audit trail is	required to tie	messages together. The	format
		 of  the  message  reference  is checked and will abort	if the
		 format	is invalid. The	option will only be accepted  if  exim
		 is running in trusted mode, not as any	regular	user.

		 The  best example of a	message	reference is when Exim sends a
		 bounce	message.  The message reference	is the	message-id  of
		 the original message for which	Exim is	sending	the bounce.

       -oMr <protocol name>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMr option sets the received protocol	value that  is	stored
		 in $received_protocol.	However, it does not apply (and	is ig-
		 nored)	when -bh or -bs	is used.  For  -bh,  the  protocol  is
		 forced	 to  one of the	standard SMTP protocol names. For -bs,
		 the protocol is always	"local-" followed by one of those same
		 names.	 For  -bS  (batched SMTP) however, the protocol	can be
		 set by	-oMr. Repeated use of this option is not supported.

       -oMs <host name>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMs  option  sets the	sender host name in $sender_host_name.
		 When this option is present, Exim does	not attempt to look up
		 a host	name from an IP	address; it uses the name it is	given.

       -oMt <ident string>
		 See -oMa above	for general remarks about the -oM options. The
		 -oMt option sets the sender ident value in $sender_ident. The
		 default  setting  for	local  callers	is the login id	of the
		 calling process, except when -bh is used, when	 there	is  no
		 default.

       -om	 In  Sendmail, this option means "me too", indicating that the
		 sender	of a message should receive a copy of the  message  if
		 the  sender  appears  in an alias expansion. Exim always does
		 this, so the option does nothing.

       -oo	 This option is	ignored. In Sendmail it	specifies  "old	 style
		 headers", whatever that means.

       -oP <path>
		 This option is	useful only in conjunction with	-bd or -q with
		 a time	value. The option specifies  the  file	to  which  the
		 process  id  of  the daemon is	written. When -oX is used with
		 -bd, or when -q with a	time is	used without -bd, this is  the
		 only  way  of	causing	 Exim  to write	a pid file, because in
		 those cases, the normal pid file is not used.

       -oPX	 This option is	not intended for general use.  The daemon uses
		 it  when terminating due to a SIGTEM, possibly	in combination
		 with -oP <path>.  It causes the pid file to be	removed.

       -or <time>
		 This option sets a timeout value for incoming	non-SMTP  mes-
		 sages.	If it is not set, Exim will wait forever for the stan-
		 dard input. The value can also	be set by the  receive_timeout
		 option.

       -os <time>
		 This  option sets a timeout value for incoming	SMTP messages.
		 The timeout applies to	each SMTP command and block  of	 data.
		 The value can also be set by the smtp_receive_timeout option;
		 it defaults to	5 minutes.

       -ov	 This option has exactly the same effect as -v.

       -oX <number or string>
		 This option is	relevant only when the	-bd  (start  listening
		 daemon) option	is also	given. It controls which ports and in-
		 terfaces the daemon uses. When	-oX is used to start a daemon,
		 no  pid file is written unless	-oP is also present to specify
		 a pid filename.

       -pd	 This option applies when  an  embedded	 Perl  interpreter  is
		 linked	  with	 Exim.	 It   overrides	 the  setting  of  the
		 perl_at_start option, forcing the starting of the interpreter
		 to be delayed until it	is needed.

       -ps	 This  option  applies	when  an  embedded Perl	interpreter is
		 linked	 with  Exim.  It  overrides   the   setting   of   the
		 perl_at_start option, forcing the starting of the interpreter
		 to occur as soon as Exim is started.

       -p<rval>:<sval>
		 For compatibility with	Sendmail, this option is equivalent to

		   -oMr	<rval> -oMs <sval>

		 It sets the incoming protocol	and  host  name	 (for  trusted
		 callers).  The	 host  name  and its colon can be omitted when
		 only the protocol is to be set.  Note the  Exim  already  has
		 two  private  options,	 -pd  and  -ps,	that refer to embedded
		 Perl. It is therefore impossible to set a protocol value of d
		 or s using this option	(but that does not seem	a real limita-
		 tion).	 Repeated use of this option is	not supported.

       -q	 This option is	normally restricted to admin  users.  However,
		 there	is  a  configuration option called prod_requires_admin
		 which can be set false	to relax this  restriction  (and  also
		 the same requirement for the -M, -R, and -S options).

		 If other commandline options do not specify an	action,	the -q
		 option	starts one queue runner	process. This scans the	 queue
		 of waiting messages, and runs a delivery process for each one
		 in turn. It waits for each delivery process to	finish	before
		 starting the next one.	A delivery process may not actually do
		 any deliveries	if the retry times for the addresses have  not
		 been  reached.	 Use  -qf  (see	below) if you want to override
		 this.

		 If the	delivery process spawns	 other	processes  to  deliver
		 other messages	down passed SMTP connections, the queue	runner
		 waits for these to finish before proceeding.

		 When all the queued messages have been	considered, the	origi-
		 nal queue runner process terminates. In other words, a	single
		 pass is made over the waiting mail, one message  at  a	 time.
		 Use  -q  with	a  time	(see below) if you want	this to	be re-
		 peated	periodically.

		 Exim processes	the waiting messages in	an  unpredictable  or-
		 der.  It  isn't very random, but it is	likely to be different
		 each time, which is all that matters.	If one particular mes-
		 sage  screws  up a remote MTA,	other messages to the same MTA
		 have a	chance of getting through if they get tried first.

		 It is possible	to cause the messages to be processed in lexi-
		 cal message id	order, which is	essentially the	order in which
		 they arrived, by setting the queue_run_in_order  option,  but
		 this is not recommended for normal use.

       -q<qflags>
		 The  -q  option  may  be followed by one or more flag letters
		 that change its behaviour. They are all optional, but if more
		 than  one  is present,	they must appear in the	correct	order.
		 Each flag is described	in a separate item below.

       -qq...	 An option starting with -qq requests a	two-stage  queue  run.
		 In   the  first  stage,  the  queue  is  scanned  as  if  the
		 queue_smtp_domains option matched every domain. Addresses are
		 routed, local deliveries happen, but no remote	transports are
		 run.  Performance will	be best	if the queue_run_in_order  op-
		 tion is false.

		 The  hints database that remembers which messages are waiting
		 for specific hosts is updated,	as if delivery to those	 hosts
		 had  been  deferred. After this is complete, a	second,	normal
		 queue scan happens, with routing and delivery taking place as
		 normal.  Messages  that  are  routed  to the same host	should
		 mostly	be delivered down a single SMTP	connection because  of
		 the hints that	were set up during the first queue scan.  This
		 option	may be useful for hosts	that are connected to the  In-
		 ternet	intermittently.

       -q[q]i... If the	i flag is present, the queue runner runs delivery pro-
		 cesses	only for those messages	that haven't  previously  been
		 tried.	(i stands for "initial delivery".) This	can be helpful
		 if you	are putting messages in	the queue using	-odq and  want
		 a queue runner	just to	process	the new	messages.

       -q[q][i]f...
		 If  one  f  flag is present, a	delivery attempt is forced for
		 each  non-frozen  message,  whereas  without  f  only	 those
		 non-frozen  addresses	that have passed their retry times are
		 tried.

       -q[q][i]ff...
		 If ff is present, a delivery attempt is forced	for every mes-
		 sage, whether frozen or not.

       -q[q][i][f[f]]l
		 The  l	 (the letter "ell") flag specifies that	only local de-
		 liveries are to be done. If a message requires	any remote de-
		 liveries, it remains in the queue for later delivery.

       -q[q][i][f[f]][l][G<name>[/<time>]]]
		 If  the  G flag and a name is present,	the queue runner oper-
		 ates on the queue with	the given name rather than the default
		 queue.	 The name should not contain a / character.  For a pe-
		 riodic	queue run (see below) append to	the name a slash and a
		 time value.

		 If  other  commandline	options	specify	an action, a -qG_name_
		 option	will specify a queue to	operate	on.  For example:

		   exim	-bp -qGquarantine
		   mailq -qGquarantine
		   exim	-qGoffpeak -Rf @special.domain.example

       -q<qflags> <start id> <end id>
		 When scanning the queue, Exim can be made to skip  over  mes-
		 sages whose ids are lexically less than a given value by fol-
		 lowing	the -q option with a starting message id. For example:

		   exim	-q 0t5C6f-0000c8-00

		 Messages that arrived earlier than 0t5C6f-0000c8-00  are  not
		 inspected.  If	 a  second message id is given,	messages whose
		 ids are lexically greater than	it are also  skipped.  If  the
		 same id is given twice, for example,

		   exim	-q 0t5C6f-0000c8-00 0t5C6f-0000c8-00

		 just  one delivery process is started,	for that message. This
		 differs from -M in that retry data is respected, and it  also
		 differs from -Mc in that it counts as a delivery from a queue
		 run. Note that	the selection mechanism	does  not  affect  the
		 order in which	the messages are scanned. There	are also other
		 ways of selecting specific sets of messages for delivery in a
		 queue run - see -R and	-S.

       -q<qflags><time>
		 When  a  time	value is present, the -q option	causes Exim to
		 run as	a daemon, starting a queue runner process at intervals
		 specified by the given	time value. This form of the -q	option
		 is commonly combined with the -bd option,  in	which  case  a
		 single	daemon process handles both functions. A common	way of
		 starting up a combined	daemon at system boot time is to use a
		 command such as

		   /usr/exim/bin/exim -bd -q30m

		 Such  a  daemon  listens  for	incoming  SMTP calls, and also
		 starts	a queue	runner process every 30	minutes.

		 When a	daemon is started by -q	with a time value, but without
		 -bd,  no  pid	file  is  written unless one is	explicitly re-
		 quested by the	-oP option.

       -qR<rsflags> <string>
		 This option is	synonymous with	-R. It is provided  for	 Send-
		 mail compatibility.

       -qS<rsflags> <string>
		 This option is	synonymous with	-S.

       -R<rsflags> <string>
		 The <rsflags> may be empty, in	which case the white space be-
		 fore the string is optional, unless the string	is f,  ff,  r,
		 rf,  or  rff,	which  are  the	possible values	for <rsflags>.
		 White space is	required if <rsflags> is not empty.

		 This option is	similar	to -q with no time value, that is,  it
		 causes	 Exim to perform a single queue	run, except that, when
		 scanning the messages on the queue, Exim processes only those
		 that have at least one	undelivered recipient address contain-
		 ing the given string, which is	checked	in a  case-independent
		 way.  If  the <rsflags> start with r, <string>	is interpreted
		 as a regular expression; otherwise it is a literal string.

		 If you	want to	do periodic queue runs for messages with  spe-
		 cific	recipients,  you  can  combine	-R  with -q and	a time
		 value.	For example:

		   exim	-q25m -R @special.domain.example

		 This example does a queue run for messages with recipients in
		 the  given domain every 25 minutes. Any additional flags that
		 are specified with -q are applied to each queue run.

		 Once a	message	is selected for	delivery  by  this  mechanism,
		 all  its addresses are	processed. For the first selected mes-
		 sage, Exim overrides any retry	information and	forces	a  de-
		 livery	 attempt for each undelivered address. This means that
		 if delivery of	any address in the first message  is  success-
		 ful, any existing retry information is	deleted, and so	deliv-
		 ery attempts for that address in subsequently	selected  mes-
		 sages	(which	are  processed without forcing)	will run. How-
		 ever, if delivery of any address does not succeed, the	 retry
		 information  is  updated,  and	 in subsequently selected mes-
		 sages,	the failing address will be skipped.

		 If the	<rsflags> contain f or ff, the	delivery  forcing  ap-
		 plies	to  all	 selected messages, not	just the first;	frozen
		 messages are included when ff is present.

		 The -R	option makes it	straightforward	to  initiate  delivery
		 of  all messages to a given domain after a host has been down
		 for some time.	When the SMTP command ETRN is accepted by  its
		 ACL,  its  default  effect is to run Exim with	the -R option,
		 but it	can be configured to run an arbitrary command instead.

       -r	 This is a documented (for Sendmail) obsolete alternative name
		 for -f.

       -S<rsflags> <string>
		 This  option  acts  like  -R except that it checks the	string
		 against each message's	sender instead of against the  recipi-
		 ents.	If  -R	is also	set, both conditions must be met for a
		 message to be selected. If either of the options has f	or  ff
		 in its	flags, the associated action is	taken.

       -Tqt <times>
		 This  is  an  option  that is exclusively for use by the Exim
		 testing suite.	It is not recognized when  Exim	 is  run  nor-
		 mally.	It allows for the setting up of	explicit "queue	times"
		 so that various warning/retry features	can be tested.

       -t	 When Exim is receiving	a locally-generated, non-SMTP  message
		 on its	standard input,	the -t option causes the recipients of
		 the message to	be obtained from the To:, Cc:, and Bcc:	header
		 lines	in  the	message	instead	of from	the command arguments.
		 The addresses are extracted before any	rewriting takes	 place
		 and the Bcc: header line, if present, is then removed.

		 If  the  command has any arguments, they specify addresses to
		 which the message is not to be	delivered. That	is, the	 argu-
		 ment  addresses are removed from the recipients list obtained
		 from the headers. This	is compatible with Smail 3 and in  ac-
		 cordance with the documented behaviour	of several versions of
		 Sendmail, as described	in man pages on	a number of  operating
		 systems  (e.g.	 Solaris 8, IRIX 6.5, HP-UX 11). However, some
		 versions of Sendmail add argument addresses to	those obtained
		 from the headers, and the O'Reilly Sendmail book documents it
		 that way. Exim	can be made to add argument addresses  instead
		 of   subtracting  them	 by  setting  the  option  extract_ad-
		 dresses_remove_arguments false.

		 If there are any Resent- header lines in  the	message,  Exim
		 extracts  recipients from all Resent-To:, Resent-Cc:, and Re-
		 sent-Bcc: header lines	instead	of from	To:,  Cc:,  and	 Bcc:.
		 This  is  for	compatibility  with  Sendmail  and other MTAs.
		 (Prior	to release 4.20, Exim gave an error if -t was used  in
		 conjunction with Resent- header lines.)

		 RFC  2822  talks about	different sets of Resent- header lines
		 (for when a message is	resent several times).	The  RFC  also
		 specifies  that they should be	added at the front of the mes-
		 sage, and separated by	Received: lines.  It  is  not  at  all
		 clear	how -t should operate in the present of	multiple sets,
		 nor indeed exactly what constitutes a "set".  In practice, it
		 seems	that MUAs do not follow	the RFC. The Resent- lines are
		 often added at	the end	of the header, and if a	message	is re-
		 sent more than	once, it is common for the original set	of Re-
		 sent- headers to be renamed as	X-Resent- when a  new  set  is
		 added.	This removes any possible ambiguity.

       -ti	 This  option  is  exactly equivalent to -t -i.	It is provided
		 for compatibility with	Sendmail.

       -tls-on-connect
		 This option is	available when Exim is compiled	with TLS  sup-
		 port. It forces all incoming SMTP connections to behave as if
		 the incoming port is listed in	the  tls_on_connect_ports  op-
		 tion.

       -U	 Sendmail  uses	 this option for "initial message submission",
		 and its documentation states that in future releases, it  may
		 complain  about  syntactically	 invalid  messages rather than
		 fixing	them when this flag is not set.	Exim ignores this  op-
		 tion.

       -v	 This  option causes Exim to write information to the standard
		 error stream, describing what it is doing. In particular,  it
		 shows	the  log lines for receiving and delivering a message,
		 and if	an SMTP	connection  is	made,  the  SMTP  dialogue  is
		 shown.	 Some of the log lines shown may not actually be writ-
		 ten to	the log	if the setting of log_selector discards	 them.
		 Any  relevant selectors are shown with	each log line. If none
		 are shown, the	logging	is unconditional.

       -x	 AIX uses -x for a private purpose ("mail from	a  local  mail
		 program  has National Language	Support	extended characters in
		 the body of the mail item").  It sets -x when calling the MTA
		 from its mail command.	Exim ignores this option.

       -X <logfile>
		 This  option is interpreted by	Sendmail to cause debug	infor-
		 mation	to be sent to the named	file.  It is ignored by	Exim.

       -z <log-line>
		 This option writes its	argument to Exim's  logfile.   Use  is
		 restricted  to	 administrators; the intent is for operational
		 notes.	 Quotes	should be used to maintain a  multi-word  item
		 as a single argument, under most shells.
