SYNOPSIS

       postqueue [-c config_dir] -f
       postqueue [-c config_dir] -p
       postqueue [-c config_dir] -s site

DESCRIPTION

       The  postqueue  program 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  mes-
       sage 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
                     hold.

       -s site
              Schedule  immediate  delivery of all mail that is queued for the
              named site. The site must be eligible for the "fast flush"  ser-
              vice.   See flush(8) for more information about the "fast flush"
              service.

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

              o      The command is invoked by the super-user.

CONFIGURATION PARAMETERS

       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-
              fix/smtpd".

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