Overview

Sender Rewriting Scheme implementation for Postfix.

Implements two TCP lookup tables to rewrite mail addresses as needed. The forward SRS is for sender envelope addresses to prevent SPF-related bounces. The reverse SRS is for recipient envelope addresses so that bounced mails can be routed back to their original sender.

`-f<port>`	set port for the forward SRS lookup (default: 10001)
`-r<port>`	set port for the reverse SRS lookup (default: 10002)
`-p<pidfile>`	write process ID to pidfile (default: none)
`-c<dir>`	chroot to <dir> (default: none)
`-u<user>`	switch user id after port bind (default: none)
`-t<seconds>`	timeout for idle client connections (default: 1800)
