Proxy protocol support

Amavis will still see the IP of the Postfix server but that's ok because you've added it to the trusted_networks list so it will look at the previous Received header to do the RBL checks. But I do my RBL checks in Postfix anyway so it doesn't matter.

Right, but you need the haproxy to be transparent, or RBLs etc. won't work in amavis? and what happens to the mail after amavis is done to it?
