POSTQUEUE(1)                                                      POSTQUEUE(1)


       postqueue - Postfix queue control


       postqueue [-c config_dir] -f
       postqueue [-c config_dir] -p
       postqueue [-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 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.


       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:

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

              ยท      The command is invoked by the super-user.


       The following parameters are especially relevant to  this  pro-

       import_environment (see โ€€™postconf -dโ€€™ output)
              The list of environment parameters that a Postfix  process  will

       trigger_timeout (10s)
