We just run postfix and amavisd-new on all our servers, and those sit behind haproxy.

You should add the IP address of the haproxy server to the trusted_networks list in Spamassassin. In my case, I'm running haproxy on the same machine as the ingress Postfix server. So I have 2 Postfix/haproxy servers and 6 amavisd servers followed by 2 Postfix egress servers. It been working great so far.
