+/* NAME
+/*	mail_addr 3
+/* SUMMARY
+/*	pre-defined mail addresses
+/* SYNOPSIS
+/*	#include <mail_addr.h>
+/*
+/*	const char *mail_addr_double_bounce()
+/*
+/*	const char *mail_addr_postmaster()
+/*
+/*	const char *mail_addr_mail_daemon()
+/* DESCRIPTION
+/*	This module predefines the following addresses:
+/* .IP MAIL_ADDR_POSTMASTER
+/*	The postmaster handle. Typically used for sending mail to.
+/* .IP MAIL_ADDR_MAIL_DAEMON
+/*	The mailer-daemon handle. Typically used to bring bad news.
+/* .IP MAIL_ADDR_EMPTY
+/*	The empty mail address. This refers to the postmaster on the
+/*	local machine.
+/* .PP
+/*	mail_addr_double_bounce() produces the fully-qualified version
+/*	of the local double bounce address.
+/*
+/*	mail_addr_postmaster() produces the fully-qualified version
+/*	of the local postmaster address.
+/*
+/*	mail_addr_mail_daemon() produces the fully-qualified version
+/*	of the local mailer-daemon address.
+/* CONFIGURATION PARAMETERS
+/*	double_bounce_sender, the double bounce pseudo account.
+/*	myhostname, the local machine hostname.
+/* BUGS
+/*	Addresses are constructed by string concatenation, instead of
+/*	passing them to the rewriting service.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
