POSTQUEUE(1)		    General Commands Manual		  POSTQUEUE(1)

       postqueue - Postfix queue control

       postqueue [-v] [-c config_dir] -f
       postqueue [-v] [-c config_dir] -i queue_id
       postqueue [-v] [-c config_dir] -p
       postqueue [-v] [-c config_dir] -s site

       The  postqueue(1)  command  implements  the  Postfix user interface for
       queue management.  It  implements  operations  that  are	 traditionally
       available  via  the  sendmail(1)	command.  See the postsuper(1) command
       for queue operations that require super-user privileges such as	delet-
       ing a message from the queue or changing	the status of a	message.

       The following options are recognized:

       -c config_dir
	      The configuration	file is	in the named directory instead
	      of the default configuration directory. See also the MAIL_CONFIG
	      environment setting below.

       -f     Flush the	queue: attempt to deliver all queued mail.

	      This option implements the traditional "sendmail -q" command, by
	      contacting the Postfix qmgr(8) daemon.

	      Warning: flushing	undeliverable mail frequently will  result  in
	      poor delivery performance	of all other mail.

       -i queue_id
	      Schedule	immediate delivery of deferred mail with the specified
	      queue ID.

	      This option implements the traditional sendmail -qI command,  by
	      contacting the flush(8) server.

	      This feature is available	with Postfix version 2.4 and later.

       -p     Produce a	traditional sendmail-style queue listing.  This	option
	      implements the traditional  mailq	 command,  by  contacting  the
	      Postfix showq(8) daemon.

	      Each  queue entry	shows the queue	file ID, message size, arrival
	      time, sender, and	the recipients that still need	to  be	deliv-
	      ered.  If	mail could not be delivered upon the last attempt, the
	      reason for failure is shown. The queue ID	string is followed  by
	      an optional status character:

	      *	     The  message  is in the active queue, i.e.	the message is
		     selected for delivery.

	      !	     The message is in the hold	queue, i.e. no further	deliv-
		     ery  attempt  will	 be  made  until the mail is taken off

       -s site
	      Schedule immediate delivery of all mail that is queued  for  the
	      named  site.  A  numerical site must be specified	as a valid RFC
	      5321 address literal enclosed in [],  just  like	in  email  ad-
	      dresses.	 The  site  must be eligible for the "fast flush" ser-
	      vice.  See flush(8) for more information about the "fast	flush"

	      This  option  implements the traditional "sendmail -qRsite" com-
	      mand, by contacting the Postfix flush(8) daemon.

       -v     Enable verbose logging for debugging purposes. Multiple  -v  op-
	      tions make the software increasingly verbose. As of Postfix 2.3,
	      this option is available for the super-user only.

       This program is designed	to run with set-group ID privileges,  so  that
       it can connect to Postfix daemon	processes.

       Problems	are logged to syslogd(8) and to	the standard error stream.

	      Directory	 with the file.	In order to avoid exploitation
	      of set-group ID privileges, a non-standard directory is  allowed
	      only if:

	      o	     The  name is listed in the	standard file with the
		     alternate_config_directories configuration	parameter.

	      o	     The command is invoked by the super-user.

       The following parameters	are especially relevant	to  this  pro-

	      The location of all postfix administrative commands.

       fast_flush_domains ($relay_domains)
	      Optional list of destinations that are eligible for per-destina-
	      tion logfiles with mail that is queued to	those destinations.

	      The  mail	 system	 name that is prepended	to the process name in
	      syslog records, so that "smtpd"  becomes,	 for  example,	"post-

       trigger_timeout (10s)
