POSTQUEUE(1)                                                      POSTQUEUE(1)



NAME
       postqueue - Postfix queue control

SYNOPSIS
       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

DESCRIPTION
       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.

       -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. 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. 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"
              service.

              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.

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

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

ENVIRONMENT
       MAIL_CONFIG
              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).

       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.
