POSTFIX(1) POSTFIX(1)

NAME

postfix - Postfix control program

SYNOPSIS

ppoossttffiixx [-DDvv] [-cc configdir] command

DESCRIPTION

This command is reserved for the superuser. To submit mail, use the Postfix sseennddmmaaiill command. The ppoossttffiixx command controls the operation of the Postfix mail system:

start or stop the mmaasstteerr daemon, do a health check, and other mainte-

nance. The ppoossttffiixx command sets up a standardized environment and runs the

ppoossttffiixx-ssccrriipptt shell script to do the actual work.

The following commands are implemented: cchheecckk Validate the Postfix mail system configuration. Warn about bad directory/file ownership or permissions, and create missing directories. ssttaarrtt Start the Postfix mail system. This also runs the configuration check described above.

ssttoopp Stop the Postfix mail system in an orderly fashion. Running pro-

cesses 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 ssttaarrtt and ssttoopp commands in succession. Use the rreellooaadd command instead. aabboorrtt Stop the Postfix mail system abruptly. Running processes are signaled to stop immediately. fflluusshh 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.

rreellooaadd Re-read configuration files. Running processes terminate at

their earliest convenience.

sseett-ppeerrmmiissssiioonnss [[name=value ...]]

Set the ownership and permissions of Postfix related files and

directories, as specified in the ppoossttffiixx-ffiilleess file.

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

figuration parameters. Use this, for example, to change the mmaaiilloowwnneerr or sseettggiiddggrroouupp setting for an already installed Postfix system. This feature is available in Postfix 2.1 and later.

uuppggrraaddee-ccoonnffiigguurraattiioonn [[name=value ...]]

Update the mmaaiinn..ccff and mmaasstteerr..ccff 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. The following options are implemented:

-cc configdir

Read the mmaaiinn..ccff and mmaasstteerr..ccff configuration files in the named directory instead of the default configuration directory. Use this to distinguish between multiple Postfix instances on the same host.

-DD (with ppoossttffiixx ssttaarrtt only)

Run each Postfix daemon under control of a debugger as specified via the ddeebbuuggggeerrccoommmmaanndd configuration parameter.

-vv Enable verbose logging for debugging purposes. Multiple -vv

options make the software increasingly verbose. ENVIRONMENT The ppoossttffiixx command exports the following environment variables before

executing the ppoossttffiixx-ssccrriipptt file:

MMAAIILLCCOONNFFIIGG

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

MMAAIILLVVEERRBBOOSSEE

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

MMAAIILLDDEEBBUUGG

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