haproxy sends session information to the server including the IP protocol, server and client IP addresses and ports. Postfix implements the haproxy version 1 protocol in both smtpd(8) and postscreen(8). http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt An alternative is to use nginx with Postfix XCLIENT support.
