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) and postqueue(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.
