+/*++
+/* NAME
+/*	error 8
+/* SUMMARY
+/*	Postfix error/retry mail delivery agent
+/* SYNOPSIS
+/*	\fBerror\fR [generic Postfix daemon options]
+/* DESCRIPTION
+/*	The Postfix \fBerror\fR(8) delivery agent processes delivery
+/*	requests from
+/*	the queue manager. Each request specifies a queue file, a sender
+/*	address, the reason for non-delivery (specified as the
+/*	next-hop destination), and recipient information.
+/*	The reason may be prefixed with an RFC 3463-compatible detail code;
+/*	if none is specified a default 4.0.0 or 5.0.0 code is used instead.
+/*	This program expects to be run from the \fBmaster\fR(8) process
+/*	manager.
+/*
+/*	Depending on the service name in master.cf, \fBerror\fR
+/*	or \fBretry\fR, the server bounces or defers all recipients
+/*	in the delivery request using the "next-hop" information
+/*	as the reason for non-delivery. The \fBretry\fR service name is
+/*	supported as of Postfix 2.4.
+/*
+/*	Delivery status reports are sent to the \fBbounce\fR(8),
+/*	\fBdefer\fR(8) or \fBtrace\fR(8) daemon as appropriate.
+/* SECURITY
+/* .ad
+/* .fi
+/*	The \fBerror\fR(8) mailer is not security-sensitive. It does not talk
+/*	to the network, and can be run chrooted at fixed low privilege.
+/* STANDARDS
+/*	RFC 3463 (Enhanced Status Codes)
+/* DIAGNOSTICS
+/*	Problems and transactions are logged to \fBsyslogd\fR(8)
+/*	or \fBpostlogd\fR(8).
+/*
+/*	Depending on the setting of the \fBnotify_classes\fR parameter,
+/*	the postmaster is notified of bounces and of other trouble.
+/* CONFIGURATION PARAMETERS
+/* .ad
+/* .fi
+/*	Changes to \fBmain.cf\fR are picked up automatically as \fBerror\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 "\fB2bounce_notice_recipient (postmaster)\fR"
+/*	The recipient of undeliverable mail that cannot be returned to
+/*	the sender.
+/* .IP "\fBbounce_notice_recipient (postmaster)\fR"
+/*	The recipient of postmaster notifications with the message headers
+/*	of mail that Postfix did not deliver and of SMTP conversation
+/*	transcripts of mail that Postfix did not receive.
+/* .IP "\fBconfig_directory (see 'postconf -d' output)\fR"
+/*	The default location of the Postfix main.cf and master.cf
+/*	configuration files.
+/* .IP "\fBdaemon_timeout (18000s)\fR"
+/*	How much time a Postfix daemon process may take to handle a
+/*	request before it is terminated by a built-in watchdog timer.
+/* .IP "\fBdelay_logging_resolution_limit (2)\fR"
+/*	The maximal number of digits after the decimal point when logging
+/*	sub-second delay values.
+/* .IP "\fBdouble_bounce_sender (double-bounce)\fR"
+/*	The sender address of postmaster notifications that are generated
+/*	by the mail system.
+/* .IP "\fBipc_timeout (3600s)\fR"
+/*	The time limit for sending or receiving information over an internal
+/*	communication channel.
+/* .IP "\fBmax_idle (100s)\fR"
+/*	The maximum amount of time that an idle Postfix daemon process waits
+/*	for an incoming connection before terminating voluntarily.
+/* .IP "\fBmax_use (100)\fR"
+/*	The maximal number of incoming connections that a Postfix daemon
+/*	process will service before terminating voluntarily.
+/* .IP "\fBnotify_classes (resource, software)\fR"
+/*	The list of error classes that are reported to the postmaster.
+/* .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 "\fBqueue_directory (see 'postconf -d' output)\fR"
+/*	The location of the Postfix top-level queue directory.
+/* .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 3.3 and later:
+/* .IP "\fBservice_name (read-only)\fR"
+/*	The master.cf service name of a Postfix daemon process.
