POSTFIX(1)                                             POSTFIX(1)


<b>NAME</b>
       postfix - Postfix control program

<b>SYNOPSIS</b>
       <b>postfix</b> [<b>-c</b> <i>config_dir</i>] [<b>-D</b>] [<b>-v</b>] <i>command</i>

<b>DESCRIPTION</b>
       The  <b>postfix</b> command controls the operation of the Postfix
       mail system: start or stop the <b>master</b> daemon, do a  health
       check,  and other maintenance. The command sets up a stan-
       dardized environment and  runs  the  <b>postfix-script</b>  shell
       script to do the actual work.

       The following commands are implemented:

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

       <b>start</b>  Start  the  Postfix mail system. This also runs the
              configuration check described above.

       <b>stop</b>   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 <b>start</b>
              and <b>stop</b> commands in  succession.  Use  the  <b>reload</b>
              command instead.

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

       <b>flush</b>  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.

       <b>reload</b> Re-read configuration files. Running processes ter-
              minate at their earliest convenience.

       The following options are implemented:

       <b>-c</b> <i>config_dir</i>
              The absolute path to a directory with Postfix  con-
              figuration  files.  Use this to distinguish between
              multiple Postfix instances on the same host.

       <b>-D</b> (with <b>postfix</b> <b>start</b> only)
              Run each Postfix daemon under control of a debugger
              as specified via the <b>debugger</b><i>_</i><b>command</b> configuration
              parameter.




                                                                1





POSTFIX(1)                                             POSTFIX(1)


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

<b>ENVIRONMENT</b>
       The <b>postfix</b> command sets the following  environment  vari-
       ables:

       <b>MAIL</b><i>_</i><b>CONFIG</b>
              Directory with Postfix configuration files.

       <b>MAIL</b><i>_</i><b>VERBOSE</b>
              This is set when the -v command-line option is pre-
              sent.

       <b>MAIL</b><i>_</i><b>DEBUG</b>
              This is set when the -D command-line option is pre-
              sent.

       The  following configuration parameters are made available
       as process environment variables with the same names:

       <b>command</b><i>_</i><b>directory</b>
              Directory with Postfix support  commands  (default:
              <b>$program</b><i>_</i><b>directory</b>).

       <b>daemon</b><i>_</i><b>directory</b>
              Directory  with  Postfix  daemon programs (default:
              <b>$program</b><i>_</i><b>directory</b>).

       <b>config</b><i>_</i><b>directory</b>
              Directory with Postfix configuration files and with
              administrative shell scripts.

       <b>queue</b><i>_</i><b>directory</b>
              The directory with the Postfix queue directory (and
              with some files needed for programs  running  in  a
              chrooted environment).

       <b>mail</b><i>_</i><b>owner</b>
              The  owner of the Postfix queue and of most Postfix
              processes.

<b>FILES</b>
       $<b>config</b><i>_</i><b>directory/postfix-script</b>, administrative commands
