Thanks Wietse, I figured that was where I was at, but was hoping there were other options I hadn't uncovered..

Postfix can get the client IP address from haproxy (uses haproxy protocol, supported in postscreen and smtpd) and from nginx (uses XCLIENT, supported in smtpd only). The client IP address is needed to for access decisions and for audit trail information (logging, headers, etc.). If your load balancer can provide that information, then I can try to add a driver to Postfix to use that information. Wietse
