POSTQUEUE(1)                                   General Commands Manual                                   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  opera‐
       tions 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 main.cf configuration file is in the named directory instead of the  default  configuration  direc‐
              tory. 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  com‐
              mand, 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 fail‐
              ure 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 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.

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

              ·      The name is listed in the standard main.cf file with the alternate_config_directories configura‐
                     tion parameter.

              ·      The command is invoked by the super-user.

CONFIGURATION PARAMETERS
       The following main.cf 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_direc‐
              tory" 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 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) dae‐
              mon).

       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.
