       bincimap.conf - Global configuration file for Binc IMAP

       A section of a bincimap.conf file might look something like this:

	      Authentication {
		  allow	plain auth in non ssl =	"no",
		  auth penalty = 4,
		  disable starttls = "no"

       This  manual  page  describes  the  format  and	content	 of  the  file
       bincimap.conf.  First comes a summary of	sections of options that users
       can set,	then we	describe the bincimap.conf structure more in detail.

       All  Binc IMAP's	configuration files use	the same Binc::Storage format.
       It's basically a	sequence of named sections enclosed in {braces},  each
       containing  a  set of comma separated key=value pairs. The keys must be
       alphanumeric, and the values can	contain	any character if it's quoted.

       Options are presented in	the format Section::name.  To set the  option,
       enter the name with no quotes in	the section as described in FORMAT be-

       The following options can be set	in bincimap.conf.

       Authentication::allow plain auth	in non ssl = [yes|no]
	      If yes, allows  plain  text  authentication  in  an  unencrypted
	      (SSL/TLS)	IMAP session.

       Authentication::auth penalty = <n>
	      Server  will  sleep for <n> seconds if the client	issues a user-
	      name/password pair that fails to authenticate.

       Log::environment	ip variable = <var>
	      Which environment	variable bincimapd should search for  the  re-
	      mote host	IP in.

       Log::syslog facility = <var>
	      If  syslog mode is used, sets the	facility to log	to. Default is
	      LOG_DAEMON. Allowed values are LOG_USER  and  LOG_LOCAL0-LOG_LO-

       Log::syslog facility number = <nr>
	      If  syslog mode is used, sets the	facility number	to log to. De-
	      fault is the value of LOG_DAEMON.

       Log::type = <type>
	      Which method Binc	IMAP should use	to log.	 syslog	means to  con-
	      nect  to	syslog.	 multilog means	to log to stderr(2). Typically
	      used together with the multilog utility. For xinetd, use syslog.
	      For daemontools/supervise, use multilog.

       Mailbox::type = <type>
	      Which  type  of  mailbox should the server use? By default, only
	      supports only Maildir.

       Mailbox::depot =	<type>
	      Which type of depot should the server use? By default,  supports
	      only IMAPdir and Maildir++.

       Mailbox::path = <path>
	      Path  to depot relative from user's home area. Typically Maildir
	      for Maildir mailboxes, or	the empty string "" if the  home  area
	      is the same as the Maildir directory.

       Mailbox::auto create inbox = [yes|no]
	      If  yes,	server	will create the	default	mailbox	INBOX on first
	      login if it does not exist.

       Mailbox::auto subscribe mailboxes = <mailboxes>
	      If present, server will automatically subscribe  client  to  the
	      given list of mailboxes on first login. Mailbox list is given as
	      a	comma separated	list with the mailbox' full path, for  example

       Mailbox::umask =	<umask>
	      Server  will  use	 this  umask  throughout  session. Defaults to
	      user's default umask.

       Security::jail path = <path>
	      Which  path  bincimap-up	should	chroot	 to   after   starting

       Security::jail user = <userid>
	      Which user bincimap-up should become after starting bincimapd.

       Security::jail group = <groupid>
	      Which group bincimap-up should enter after starting bincimapd.

       Security::version in greeting = [yes|no]
	      When  set	to "yes", Binc IMAP will display its version number in
	      the greeting displayed to	clients	when they  connect;  otherwise
	      no  version  number  is displayed. This version number is	useful
	      for debugging and	identifying the	service, but it	is also	useful
	      for  malicious  users  who  wish to identify versions to exploit
	      known security holes.

       Session::idle timeout = <n>
	      When the server is in authenticated mode,	and  does  not	detect
	      any  client  activity,  it  will wait <n>	seconds	before closing
	      (t/o) the	connection. <n>	can not	be less	than 1800 seconds.

       Session::auth timeout = <n>
	      When the server is in unauthenticated mode, and does not	detect
	      any  client  activity,  it  will wait <n>	seconds	before closing
	      (t/o) the	connection. <n>	can not	be less	than 30	seconds.

       Session::transfer timeout = <n>
	      The server writes	data to	the client in bulks.  Each  bulk  gets
	      <n> seconds to complete before the server	times out.

       Session::transfer buffer	size = <n>
	      The server will buffer up	to <n> bytes of	data before sending it
	      off to the client. A lower value	will  give  smoother  response
	      from  the	 server,  but is a bad idea for	clients	with a big RTT
	      (for example dial-ins). A	high value  gives  better  throughput,
	      but a more bulky transfer.

       SSL::pem	file = <file>
	      The path to the SSL certificate file, in PEM format.

       SSL::ca file = <file>
	      A	 file  with one	or more	certificate authority certificates. It
	      is used to help the client verify	the SSL	certificate.

       SSL::ca path = <path>
	      A	path with lists	of certificate authorities' cerficates.	It  is
	      used to help the client verify the SSL certificate.

       SSL::cipher list	= <cipherlist>
	      Sets the list of available SSL ciphers.

       SSL::verify peer	= [yes|no]
	      If yes, server will attempt to verify peer certificate.

       This file format	is named Binc::Storage,	after its C++ class name.

       The  file  starts with an optional list of aliases. These aliases start
       with a question mark '?', followed by the alias,	a colon	':',  the  re-
       placement  text,	 and finally a semicolon ';'. This example defines the
       alias "m" to represent the text "myfirstsection":


       A section starts	with an	identifier, or a name. The name	contains  only
       alphanumeric characters,	and it's case sensitive. The section itself is
       enclosed	in braces.

	      MyFirstSection {


       Inside a	section, we have a comma separated list	 of  key=value	pairs.
       The  key	 consists of a sequence	of one or more alphanumeric words. The
       value can also contain quoted strings.

	      MyFirstSection {
		certificate path = "/etc/path/certificate.txt",
		optional argument = "yes"

       The aliases that	we could define	at the start of	the bincimap.conf file
       are  useful  if	we  wish  to abbreviate	long words in a	key or section
       name, to	save space. Normally this is only used in generated files, but
       they can	also make a manually edited conf file more compact:

	      m	{
		certificate path = "/etc/path/certificate.txt",
		optional argument = "yes"
