+/* NAME
+/*	test-milter 1
+/* SUMMARY
+/*	Simple test mail filter program.
+/* SYNOPSIS
+/* .fi
+/*	\fBtest-milter\fR [\fIoptions\fR] -p \fBinet:\fIport\fB@\fIhost\fR
+/*
+/*	\fBtest-milter\fR [\fIoptions\fR] -p \fBunix:\fIpathname\fR
+/* DESCRIPTION
+/*	\fBtest-milter\fR is a Milter (mail filter) application that
+/*	exercises selected features.
+/*
+/*	Note: this is an unsupported test program. No attempt is made
+/*	to maintain compatibility between successive versions.
+/*
+/*	Arguments (multiple alternatives are separated by "\fB|\fR"):
+/* .IP "\fB-a accept|tempfail|reject|discard|skip|\fIddd x.y.z text\fR"
+/*	Specifies a non-default reply for the MTA command specified
+/*	with \fB-c\fR. The default is \fBtempfail\fR. The \fItext\fR
+/*	is repeated once, to produce multi-line reply text.
+/* .IP "\fB-A address\fR"
+/*	Add the specified recipient address (specify ESMTP parameters
+/*	separated by space). Multiple -A options are supported.
+/* .IP "\fB-b pathname\fR"
+/*	Replace the message body by the content of the specified file.
+/* .IP "\fB-c connect|helo|mail|rcpt|data|header|eoh|body|eom|unknown|close|abort\fR"
+/*	When to send the non-default reply specified with \fB-a\fR.
+/*	The default protocol stage is \fBconnect\fR.
+/* .IP "\fB-C\fI count\fR"
+/*	Terminate after \fIcount\fR connections.
+/* .IP "\fB-d\fI level\fR"
+/*	Enable libmilter debugging at the specified level.
+/* .IP "\fB-D\fI address\fR"
+/*	Delete the specified recipient address. Multiple -D options
+/*	are supported.
+/* .IP "\fB-f \fIsender\fR"
+/*	Replace the sender by the specified address.
+/* .IP "\fB-h \fI'index header-label header-value'\fR"
+/*	Replace the message header at the specified position.
+/* .IP "\fB-i \fI'index header-label header-value'\fR"
+/*	Insert header at specified position.
+/* .IP "\fB-l\fR"
+/*	Header values include leading space. Specify this option
+/*	before \fB-i\fR or \fB-h\fR.
+/* .IP "\fB-m connect|helo|mail|rcpt|data|eoh|eom\fR"
+/*	The protocol stage that receives the list of macros specified
+/*	with \fB-M\fR.  The default protocol stage is \fBconnect\fR.
+/* .IP "\fB-M \fIset_macro_list\fR"
+/*	A non-default list of macros that the MTA should send at
+/*	the protocol stage specified with \fB-m\fR.
+/* .IP "\fB-n connect|helo|mail|rcpt|data|header|eoh|body|eom|unknown\fR"
+/*	The event that the MTA should not send.
+/* .IP "\fB-N connect|helo|mail|rcpt|data|header|eoh|body|eom|unknown\fR"
+/*	The event for which the filter will not reply.
+/* .IP "\fB-p inet:\fIport\fB@\fIhost\fB|unix:\fIpathname\fR"
+/*	The mail filter listen endpoint.
+/* .IP "\fB-r\fR"
+/*	Request rejected recipients from the MTA.
+/* .IP "\fB-v\fR"
+/*	Make the program more verbose.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
