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 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 post-
       fix-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 com-
       mand 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 directo-
	      ries.

       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 imme-
	      diately.

       flush  Force  delivery:	attempt to deliver every message in the deferred mail queue. Nor-
	      mally, 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 per-
	      formance of all other mail.

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

       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  parame-
	      ters.  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  parame-
	      ters.

	      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) com-
	      mands 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  debug-
	      ger_command configuration parameter.

       -v     Enable  verbose  logging for debugging purposes. Multiple -v options make the soft-
	      ware 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.

       The  following main.cf configuration parameters are exported as environment variables with
       the same names:

       names into their actual values.
