 POSTLOGD 8

 NAME
postlogd
-
Postfix internal log server
 "SYNOPSIS"
postlogd [generic Postfix daemon options]
 DESCRIPTION

This program logs events on behalf of Postfix programs
when the maillog configuration parameter specifies a non-empty
value.
 BUGS

Non-daemon Postfix programs don't know that they should log
to the internal logging service before they have processed
command-line options and main.cf parameters. These programs
still log earlier events to the syslog service.

If Postfix is down, the non-daemon programs postfix(1),
postsuper(1), postmulti(1), and postlog(1),
will log directly to $maillog_file. These programs
expect to run with root privileges, for example during
Postfix start-up, reload, or shutdown.

Other non-daemon Postfix programs will never write directly to
$maillog_file (also, logging to stdout would interfere
with the operation of some of these programs). These programs
can log to postlogd(8) if they are run by the super-user,
or if their executable file has set-gid permission. Do not
set this permission on programs other than postdrop(1),
postqueue(1) and (Postfix >= 3.7) postlog(1).
 "CONFIGURATION PARAMETERS"

Changes to main.cf are picked up automatically, as
postlogd(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.
 "maillog_file (empty)"
The name of an optional logfile that is written by the Postfix
postlogd(8) service.
 "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.
 "syslog_name (see 'postconf -d' output)"
A prefix that is prepended to the process name in syslog
records, so that, for example, "smtpd" becomes "prefix/smtpd".
 "service_name (read-only)"
The master.cf service name of a Postfix daemon process.
 "postlogd_watchdog_timeout (10s)"
How much time a postlogd(8) process may take to process a request
before it is terminated by a built-in watchdog timer.
