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.
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 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.
CONFIGURATION PARAMETERS
The following main.cf configuration parameters are exported as environ-
ment variables with the same names:
command_directory (see 'postconf -d' output)
The location of all postfix administrative commands.
daemon_directory (see 'postconf -d' output)
The directory with Postfix support programs and daemon programs.
config_directory (see 'postconf -d' output)
The default location of the Postfix main.cf and master.cf con-
figuration files.
queue_directory (see 'postconf -d' output)
The location of the Postfix top-level queue directory.
mail_owner (postfix)
The UNIX system account that owns the Postfix queue and most
Postfix daemon processes.
setgid_group (postdrop)
The group ownership of set-gid Postfix commands and of group-
writable Postfix directories.
sendmail_path (see 'postconf -d' output)
A Sendmail compatibility feature that specifies the location of
the Postfix sendmail(1) command.
newaliases_path (see 'postconf -d' output)
Sendmail compatibility feature that specifies the location of
the newaliases(1) command.
mailq_path (see 'postconf -d' output)
Sendmail compatibility feature that specifies where the Postfix
mailq(1) command is installed.
html_directory (see 'postconf -d' output)
The location of Postfix HTML files that describe how to build,
configure or operate a specific Postfix subsystem or feature.
manpage_directory (see 'postconf -d' output)
Where the Postfix manual pages are installed.
readme_directory (see 'postconf -d' output)
The location of Postfix README files that describe how to build,
configure or operate a specific Postfix subsystem or feature.
Available in Postfix version 2.5 and later:
data_directory (see 'postconf -d' output)
The directory with Postfix-writable data files (for example:
caches, pseudo-random numbers).
Other configuration parameters:
config_directory (see 'postconf -d' output)
The default location of the Postfix main.cf and master.cf con-
figuration files.
import_environment (see 'postconf -d' output)
The list of environment parameters that a Postfix process will
import from a non-Postfix parent process.
syslog_facility (mail)
The syslog facility of Postfix logging.
syslog_name (postfix)
The mail system name that is prepended to the process name in
syslog records, so that "smtpd" becomes, for example, "post-
fix/smtpd".
