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
       system:  start  or  stop  the  master(8) daemon, do a health check, and
       other maintenance.

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

       However,  when  support  for  multiple Postfix instances is configured,
       postfix(1)    executes    the    command     specified     with     the
       multi_instance_wrapper  configuration  parameter.   This  command  will
       execute the command for each applicable Postfix instance.

       The following commands are implemented:

       check  Warn about bad  directory/file  ownership  or  permissions,  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. If possible,
              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  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
              configuration 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
              Postfix  2.0  and  earlier,  use "$config_directory/post-install
              set-permissions".

       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
              configuration parameters.

              This  feature  is  available  in  Postfix  2.1  and later.  With
              Postfix 2.0  and  earlier,  use  "$config_directory/post-install
              upgrade-configuration".

       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.

              With Postfix 2.6 and later, this option  forces  the  postfix(1)
              command to operate on the specified Postfix instance only.  This
              behavior is inherited by  postfix(1)  commands  that  run  as  a
              descendant of the current process.

       -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.

              With Postfix 2.6 and later, this environment variable forces the
              postfix(1)  command to operate on the specified Postfix instance
              only.  This behavior is inherited by  postfix(1)  commands  that
              run as a descendant of the current process.

       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.

FILES

       Prior to Postfix version 2.6,  all  of  the  following  files  were  in
       $config_directory. Some files are now in $daemon_directory so that they
       can be shared among  multiple  instances  that  run  the  same  Postfix
       version.

       Use    the    command    "postconf   config_directory"   or   "postconf
       daemon_directory" to expand the names into their actual values.
