NAME
postsrsd - Postfix Sender Rewriting Scheme daemon
SYNOPSIS
postsrsd -s<file> -d<domain> [other options]
DESCRIPTION
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.
