+.SH NAME
+postlogd
+\-
+Postfix internal log server
+.SH "SYNOPSIS"
+.na
+.nf
+\fBpostlogd\fR [generic Postfix daemon options]
+.SH DESCRIPTION
+.ad
+.fi
+This program logs events on behalf of Postfix programs
+when the maillog configuration parameter specifies a non\-empty
+value.
+.SH BUGS
+.ad
+.fi
+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 \fBpostfix\fR(1),
+\fBpostsuper\fR(1), \fBpostmulti\fR(1), and \fBpostlog\fR(1),
+will log directly to \fB$maillog_file\fR. These programs
+expect to run with root privileges, for example during
+Postfix start\-up, reload, or shutdown.
+
+Other non\-daemon Postfix programs will never write directly to
+\fB$maillog_file\fR (also, logging to stdout would interfere
+with the operation of some of these programs). These programs
+can log to \fBpostlogd\fR(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 \fBpostdrop\fR(1),
+\fBpostqueue\fR(1) and (Postfix >= 3.7) \fBpostlog\fR(1).
+.SH "CONFIGURATION PARAMETERS"
+.na
+.nf
+.ad
+.fi
+Changes to \fBmain.cf\fR are picked up automatically, as
+\fBpostlogd\fR(8) processes run for only a limited amount
+of time. Use the command "\fBpostfix reload\fR" to speed
+up a change.
+
+The text below provides only a parameter summary. See
+\fBpostconf\fR(5) for more details including examples.
+.IP "\fBconfig_directory (see 'postconf -d' output)\fR"
+The default location of the Postfix main.cf and master.cf
+configuration files.
+.IP "\fBmaillog_file (empty)\fR"
+The name of an optional logfile that is written by the Postfix
+\fBpostlogd\fR(8) service.
+.IP "\fBprocess_id (read\-only)\fR"
+The process ID of a Postfix command or daemon process.
+.IP "\fBprocess_name (read\-only)\fR"
+The process name of a Postfix command or daemon process.
+.IP "\fBsyslog_name (see 'postconf -d' output)\fR"
+A prefix that is prepended to the process name in syslog
+records, so that, for example, "smtpd" becomes "prefix/smtpd".
+.IP "\fBservice_name (read\-only)\fR"
+The master.cf service name of a Postfix daemon process.
+.IP "\fBpostlogd_watchdog_timeout (10s)\fR"
+How much time a \fBpostlogd\fR(8) process may take to process a request
+before it is terminated by a built\-in watchdog timer.
