+/* 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
