POSTLOGD(8) System Manager's Manual 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 $mail-
log_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 per-
mission. Do not set this permission on programs other than postdrop(1)
and postqueue(1).
CONFIGURATION PARAMETERS
Changes to main.cf are picked up automatically, as postlogd(8) pro-
cesses 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 con-
figuration 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.
