That's how I run it now, but amavisd sees the haproxy IP when it 
connects, and not the IP of the ingress server?

What I'd like is:

--> postfix (in, port 25) --> haproxy --> amavisd --> postfix (in, port 
10025)

But amavisd doesnt know what postfix server to return the mail to (I 
have multiple, but want central amavis cluster), because it only sees 
the haproxy IP.

Does that make sense? :)

Thanks
