+/*++
+/* 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.
+/* SECURITY
+/* .ad
+/* .fi
+/* The \fBpostlog\fR(1) command is designed to run with
+/* set-groupid privileges, so that it can connect to the
+/* \fBpostlogd\fR(8) daemon process (Postfix 3.7 and later;
+/* earlier implementations of this command must not have
+/* set-groupid or set-userid permissions).
+/* 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.
+/* SEE ALSO
+/* postconf(5), configuration parameters
+/* postlogd(8), Postfix logging
+/* syslogd(8), system logging
+/* LICENSE
+/* .ad
+/* .fi
+/* The Secure Mailer license must be distributed with this software.
+/* HISTORY
+/* The \fBpostlog\fR(1) command was introduced with Postfix
+/* version 3.4.
