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.

       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.
