/* 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.
