POSTQUEUE(1)                                                      POSTQUEUE(1)

       postqueue - Postfix queue control

       <b>postqueue</b> [<b>-v</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] <b>-f</b>

       The  <a href="postqueue.1.html"><b>postqueue</b>(1)</a>  command  implements  the  Postfix  user
       interface for queue management. It  implements  operations
       that  are traditionally available via the <a href="sendmail.1.html"><b>sendmail</b>(1)</a> com-
       mand.  See the <a href="postsuper.1.html"><b>postsuper</b>(1)</a> 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:

       <b>-c</b> <i>config</i><b>_</b><i>dir</i>
              The <a href="postconf.5.html"><b></b></a> configuration  file  is  in  the  named
              directory  instead  of  the  default  configuration
              directory. See  also  the  MAIL_CONFIG  environment
              setting below.

       <b>-f</b>     Flush  the  queue:  attempt  to  deliver all queued

              This option implements  the  traditional  "<b>sendmail</b>
              <b>-q</b>" command, by contacting the Postfix <a href="qmgr.8.html"><b>qmgr</b>(8)</a> dae-

              Warning:  flushing  undeliverable  mail  frequently
              will  result  in  poor  delivery performance of all
              other mail.

       <b>-i</b> <i>queue</i><b>_</b><i>id</i>
              Schedule immediate delivery of deferred  mail  with
              the specified queue ID.

              This option implements the traditional <b>sendmail -qI</b>
              command, by contacting the <a href="flush.8.html"><b>flush</b>(8)</a> server.

              This feature is available with Postfix version  2.4
              and later.

       <b>-p</b>     Produce a traditional sendmail-style queue listing.
              This option implements the traditional  <b>mailq</b>  com-
              mand, by contacting the Postfix <a href="showq.8.html"><b>showq</b>(8)</a> 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. This mode of operation is imple-
              mented by executing the <a href="postqueue.1.html"><b>postqueue</b>(1)</a>  command.  The
              queue  ID  string is followed by an optional status

              <b>*</b>      The message is in the <b>active</b> queue, i.e. the
                     message is selected for delivery.

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

       <b>-s</b> <i>site</i>
              Schedule  immediate  delivery  of  all mail that is
              queued for the named <i>site</i>. A numerical site must be
              specified  as  a  valid  <a href="">RFC  2821</a>  address literal
              enclosed in [], just like in email addresses.   The
              site must be eligible for the "fast flush" service.
              See <a href="flush.8.html"><b>flush</b>(8)</a> for more information about  the  "fast
              flush" service.

              This  option  implements  the traditional "<b>sendmail</b>
              <b>-qR</b><i>site</i>"  command,  by   contacting   the   Postfix
              <a href="flush.8.html"><b>flush</b>(8)</a> daemon.

       <b>-v</b>     Enable verbose logging for debugging purposes. Mul-
              tiple <b>-v</b> options  make  the  software  increasingly
              verbose.  As  of Postfix 2.3, this option is avail-
              able for the super-user only.

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

       Problems are logged to  <b>syslogd</b>(8)  and  to  the  standard
       error stream.

              Directory  with the <a href="postconf.5.html"><b></b></a> file. In order to avoid
              exploitation of set-group  ID  privileges,  a  non-
              standard directory is allowed only if:

              <b>o</b>      The  name  is listed in the standard <a href="postconf.5.html"><b></b></a>
                     file with  the  <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b>
                     configuration parameter.

              <b>o</b>      The command is invoked by the super-user.

       The  following  <a href="postconf.5.html"><b></b></a> parameters are especially relevant
       to this program.  The text below provides only a parameter
       summary.  See <a href="postconf.5.html"><b>postconf</b>(5)</a> for more details including exam-
