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.
