+/*++
+/* NAME
+/*	postlog 1
+/* SUMMARY
+/*	Postfix-compatible logging utility
+/* SYNOPSIS
+/* .fi
+/* .ad
+/*	\fBpostlog\fR [\fB-iv\fR] [\fB-c \fIconfig_dir\fR]
+/*	[\fB-p \fIpriority\fR] [\fB-t \fItag\fR] [\fItext...\fR]
+/* DESCRIPTION
+/*	The \fBpostlog\fR(1) command implements a Postfix-compatible logging
+/*	interface for use in, for example, shell scripts.
+/*
+/*	By default, \fBpostlog\fR(1) logs the \fItext\fR given on the command
+/*	line as one record. If no \fItext\fR is specified on the command
+/*	line, \fBpostlog\fR(1) reads from standard input and logs each input
+/*	line as one record.
+/*
+/*	By default, logging is sent to \fBsyslogd\fR(8) or
+/*	\fBpostlogd\fR(8); when the
+/*	standard error stream is connected to a terminal, logging
+/*	is sent there as well.
+/*
+/*	The following options are implemented:
+/* .IP "\fB-c \fIconfig_dir\fR"
+/*	Read the \fBmain.cf\fR configuration file in the named directory
+/*	instead of the default configuration directory.
+/* .IP "\fB-i\fR (obsolete)"
+/*	Include the process ID in the logging tag. This flag is ignored as
+/*	of Postfix 3.4, where the PID is always included.
+/* .IP "\fB-p \fIpriority\fR (default: \fBinfo\fR)"
+/*	Specifies the logging severity: \fBinfo\fR, \fBwarn\fR,
+/*	\fBerror\fR, \fBfatal\fR, or \fBpanic\fR. With Postfix 3.1
+/*	and later, the program will pause for 1 second after reporting
+/*	a \fBfatal\fR or \fBpanic\fR condition, just like other
+/*	Postfix programs.
+/* .IP "\fB-t \fItag\fR"
+/*	Specifies the logging tag, that is, the identifying name that
+/*	appears at the beginning of each logging record. A default tag
+/*	is used when none is specified.
+/* .IP \fB-v\fR
+/*	Enable verbose logging for debugging purposes. Multiple \fB-v\fR
+/*	options make the software increasingly verbose.
+/* ENVIRONMENT
+/* .ad
+/* .fi
+/* .IP MAIL_CONFIG
+/*	Directory with the \fBmain.cf\fR file.
+/* CONFIGURATION PARAMETERS
+/* .ad
+/* .fi
+/*	The following \fBmain.cf\fR parameters are especially relevant to
+/*	this program.
+/*
+/*	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 "\fBimport_environment (see 'postconf -d' output)\fR"
+/*	The list of environment parameters that a privileged Postfix
+/*	process will import from a non-Postfix parent process, or name=value
+/*	environment overrides.
+/* .IP "\fBsyslog_facility (mail)\fR"
+/*	The syslog facility of Postfix logging.
+/* .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".
+/* .PP
+/*	Available in Postfix 3.4 and later:
+/* .IP "\fBmaillog_file (empty)\fR"
+/*	The name of an optional logfile that is written by the Postfix
+/*	\fBpostlogd\fR(8) service.
+/* .IP "\fBpostlog_service_name (postlog)\fR"
+/*	The name of the \fBpostlogd\fR(8) service entry in master.cf.

+/*++
+/* NAME
+/*	postlogd 8
+/* SUMMARY
+/*	Postfix internal log server
+/* SYNOPSIS
+/*	\fBpostlogd\fR [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 \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)
+/*	and \fBpostqueue\fR(1).
+/* CONFIGURATION PARAMETERS
+/* .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.
+/* SEE ALSO
