       postqueue - Postfix queue control

       postqueue [-v] [-c config_dir] -f
       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 main.cf 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.

       -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. This mode of  operation  is	imple
	      mented  by  executing  the  postqueue(1)	command.  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
	      2821  address  literal  enclosed	in  [],  just  like  in  email
	      addresses.  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
	      options 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 main.cf file. In order to avoid  exploitation
	      of  set-group ID privileges, a non-standard directory is allowed
	      only if:

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

		    The command is invoked by the super-user.

       The  following  main.cf parameters are especially relevant to this pro
       gram.  The text below provides only  a  parameter  summary.  See  post
       conf(5) for more details including examples.

       alternate_config_directories (empty)
	      A list of non-default Postfix configuration directories that may
	      be specified with "-c config_directory" on the command line,  or
	      via the MAIL_CONFIG environment parameter.

       config_directory (see postconf -d output)
	      The  default  location of the Postfix main.cf and master.cf con
	      figuration files.

       command_directory (see postconf -d output)
	      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.

       import_environment (see postconf -d output)
	      The  list  of environment parameters that a Postfix process will
	      import from a non-Postfix parent process.

       queue_directory (see postconf -d output)
	      The location of the Postfix top-level queue directory.

       syslog_facility (mail)
	      The syslog facility of Postfix logging.

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

       trigger_timeout (10s)
	      The time limit for sending a trigger to a  Postfix  daemon  (for
	      example, the pickup(8) or qmgr(8) daemon).

       Available in Postfix version 2.2 and later:

       authorized_flush_users (static:anyone)
	      List of users who are authorized to flush the queue.

       authorized_mailq_users (static:anyone)
	      List of users who are authorized to view the queue.

       /var/spool/postfix, mail queue

       qmgr(8), queue manager
       showq(8), list mail queue
       flush(8), fast flush service
       sendmail(1), Sendmail-compatible user interface
       postsuper(1), privileged queue operations

       this information.
