POSTQUEUE(1)                                                      POSTQUEUE(1)




NAME

       postqueue - Postfix queue control


SYNOPSIS

       postqueue [-c config_dir] -f
       postqueue [-c config_dir] -p
       postqueue [-c config_dir] -s site


DESCRIPTION

       The  postqueue  program 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  mes-
       sage 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.

       -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. 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 command,
              by contacting the Postfix flush(8) daemon.

       -v     Enable verbose  logging  for  debugging  purposes.  Multiple  -v
              options make the software increasingly verbose.


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, it is
              not possible to specify arbitrary directory names.

              A  non-standard  directory is allowed only if the name is listed
              in the standard main.cf file, in  the  alternate_config_directo-
              ries configuration parameter value.

              Only  the  superuser  is  allowed to specify arbitrary directory
              names.


FILES

       /var/spool/postfix, mail queue
       /etc/postfix, configuration files


CONFIGURATION PARAMETERS

       import_environment
              List of names of environment parameters  that  can  be  imported
              from non-Postfix processes.

       queue_directory
              Top-level  directory of the Postfix queue. This is also the root
              directory of Postfix daemons that run chrooted.

       fast_flush_domains
              List of domains that will receive "fast flush" service (default:
              all  domains that this system is willing to relay mail to). This
              list specifies the domains that Postfix accepts in the SMTP ETRN
              request and in the sendmail -qR command.
