POSTLOGD(8)            DragonFly 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
       $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.
