       postqueue - Postfix queue control


       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


       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
       deleting  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.

       -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
              delivered.  If  mail  could  not  be  delivered  upon  the  last
              attempt, the reason for failure 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

       -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"
              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.

       -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.


       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:

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

              ·      The command is invoked by the super-user.

       import_environment (seepostconf -doutput)
              The list of environment parameters that a Postfix  process  will
