       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
       deleting 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 delivered.  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

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

       -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 addresses.  The site must be eligible for the  "fast  flush"
              service.  See flush(8) for more information about the "fast flush" service.

              This  option  implements  the traditional "sendmail -qRsite" command, 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  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   file   with   the
                     alternate_config_directories configuration parameter.

              •      The command is invoked by the super-user.


       The  following parameters are especially relevant to this program.  The text below
       provides only a parameter summary. See postconf(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

       config_directory (see 'postconf -d' output)
              The default location of the Postfix and configuration 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-destination  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 (see 'postconf -d' output)
              The mail system name that is prepended to the process name in  syslog  records,  so
              that "smtpd" becomes, for example, "postfix/smtpd".

       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)

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