+/* NAME
+/*	input_transp 3
+/* SUMMARY
+/*	receive transparency control
+/* SYNOPSIS
+/*	#include <input_transp.h>
+/*
+/*	int	input_transp_mask(param_name, pattern)
+/*	const char *param_name;
+/*	const char *pattern;
+/*
+/*	int	input_transp_cleanup(cleanup_flags, transp_mask)
+/*	int	cleanup_flags;
+/*	int	transp_mask;
+/* DESCRIPTION
+/*	This module controls how much processing happens before mail is
+/*	written to the Postfix queue. Each transparency option is either
+/*	implemented by a client of the cleanup service, or is passed
+/*	along in a client request to the cleanup service. This eliminates
+/*	the need to configure multiple cleanup service instances.
+/*
+/*	input_transp_mask() takes a comma-separated list of names and
+/*	computes the corresponding mask. The following names are
+/*	recognized in \fBpattern\fR, with the corresponding bit mask
+/*	given in parentheses:
+/* .IP "no_unknown_recipient_checks (INPUT_TRANSP_UNKNOWN_RCPT)"
+/*	Do not try to reject unknown recipients.
+/* .IP "no_address_mappings (INPUT_TRANSP_ADDRESS_MAPPING)"
+/*	Disable canonical address mapping, virtual alias map expansion,
+/*	address masquerading, and automatic BCC recipients.
+/* .IP "no_header_body_checks (INPUT_TRANSP_HEADER_BODY)"
+/*	Disable header/body_checks.
+/* .IP "no_milters (INPUT_TRANSP_MILTER)"
+/*	Disable Milter applications.
+/*
+/*	input_transp_cleanup() takes a bunch of cleanup processing
+/*	flags and updates them according to the settings in the
+/*	specified input transparency mask.
+/* DIAGNOSTICS
+/*	Panic: inappropriate use.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
