POSTFIX(1)                                                          POSTFIX(1)



NAME
       postfix - Postfix control program

SYNOPSIS
       postfix [-Dv] [-c config_dir] command

DESCRIPTION
       This  command  is  reserved  for the superuser. To submit mail, use the
       Postfix sendmail(1) command.

       The postfix(1) command controls the operation of the Postfix mail  sys-
       tem:  start  or stop the master(8) daemon, do a health check, and other
       maintenance.

       The postfix(1) command sets up a standardized environment and runs  the
       postfix-script shell script to do the actual work.

       The following commands are implemented:

       check  Warn about bad directory/file ownership or permissions, and cre-
              ate 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. If possible,
              running processes are allowed to  terminate  at  their  earliest
              convenience.

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

       abort  Stop  the  Postfix  mail  system abruptly. Running processes 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.

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

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

       status Indicate if the Postfix mail system is currently running.

       set-permissions [name=value ...]
              Set  the  ownership and permissions of Postfix related files and
              directories, as specified in the postfix-files file.

              Specify name=value to override and update specific main.cf  con-
              figuration  parameters.  Use  this,  for  example, to change the
              mail_owner or setgid_group  setting  for  an  already  installed
              Postfix system.

              This  feature is available in Postfix 2.1 and later.  With Post-
              fix 2.0 and earlier, use "/etc/postfix/post-install  set-permis-
              sions".

       upgrade-configuration [name=value ...]
              Update  the  main.cf  and  master.cf files with information that
              Postfix needs in order to run: add or update services,  and  add
              or update configuration parameter settings.

              Specify  name=value to override and update specific main.cf con-
              figuration parameters.

              This feature is available in Postfix 2.1 and later.  With  Post-
              fix 2.0 and earlier, use "/etc/postfix/post-install upgrade-con-
              figuration".

       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 configuration directory.  Use
              this to distinguish between multiple Postfix  instances  on  the
              same 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.  Multiple  -v
              options make the software increasingly verbose.

ENVIRONMENT
       The  postfix(1)  command  exports  the  following environment variables
       before executing the postfix-script file:

       MAIL_CONFIG
              This is set when the -c command-line option is present.

       MAIL_VERBOSE
              This is set when the -v command-line option is present.

       MAIL_DEBUG
              This is set when the -D command-line option is present.
