POSTFIX(1)                                             POSTFIX(1)


NAME
       postfix - Postfix control program

SYNOPSIS
       postfix [-c config_dir] [-D] [-v] command

DESCRIPTION
       This  command  is  reserved  for the super-user. To submit
       mail, use the Postfix sendmail command.

       The postfix command controls the operation of the  Postfix
       mail  system: start or stop the master daemon, do a health
       check, and other maintenance.

       The postfix command sets up a standardized environment and
       runs  the  postfix-script  shell  script  to do the actual
       work.

       The following commands are implemented:

       check  Validate the  Postfix  mail  system  configuration.
              Warn  about bad directory/file ownership or permis-
              sions, and create missing directories.

       start  Start the Postfix mail system. This also  runs  the
              configuration check described above.

       stop   Stop the Postfix mail system in an orderly fashion.
              Running processes are allowed to terminate at their
              earliest convenience.

              Note:  in  order to refresh the Postfix mail system
              after a configuration change, do not use the  start
              and  stop  commands  in  succession. Use the reload
              command instead.

       abort  Stop the Postfix mail system abruptly. Running pro-
              cesses are signaled to stop immediately.

       flush  Force delivery: attempt to deliver every message in
              the deferred  mail  queue.  Normally,  attempts  to
              deliver  delayed  mail happen at regular intervals,
              the interval doubling after each failed attempt.

       reload Re-read configuration files. Running processes ter-
              minate at their earliest convenience.

       The following options are implemented:

       -c config_dir
              Read  the main.cf and master.cf configuration files
              in the named directory instead of the default  con-
              figuration  directory.   Use  this  to  distinguish
              between multiple  Postfix  instances  on  the  same



                                                                1

              host.

       -D (with postfix start only)
              Run each Postfix daemon under control of a debugger
              as specified via the debugger_command configuration
              parameter.

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

              sent.
