Manuel SHOWQ

The showq(8) daemon can also be run in stand-alone mode by the superuser. This mode of operation is used to emulate the `mailq' command while the Postfix mail system is down.

The showq(8) daemon can run in a chroot jail at fixed low privilege, and takes no input from the client. Its service port is accessible to local untrusted users, so the service can be susceptible to denial of service attacks.

Changes to main.cf are picked up automatically as showq(8) processes run for only a limited amount of time. Use the command "postfix reload" to speed up a change.

The text below provides only a parameter summary. See postconf(5) for more details including examples.


config_directory (see 'postconf -d' output): The default location of the Postfix main.cf and master.cf configuration files.

daemon_timeout (18000s): How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer.

duplicate_filter_limit (1000): The maximal number of addresses remembered by the address duplicate filter for aliases(5) or virtual(5) alias expansion, or for showq(8) queue displays.

empty_address_recipient (MAILER-DAEMON): The recipient of mail addressed to the null address.

ipc_timeout (3600s): The time limit for sending or receiving information over an internal communication channel.

max_idle (100s): The maximum amount of time that an idle Postfix daemon process waits for an incoming connection before terminating voluntarily.

max_use (100): The maximal number of incoming connections that a Postfix daemon process will service before terminating voluntarily.

process_id (read-only): The process ID of a Postfix command or daemon process.

process_name (read-only): The process name of a Postfix command or daemon process.

queue_directory (see 'postconf -d' output): The location of the Postfix top-level queue directory.

syslog_facility (mail): The syslog facility of Postfix logging.
