I'm trying to set up iredmail as a frontend spam filter for Exchange. I use iredmail-pro for a bunch of my personal domains so I see in there where to forward emails, but how do I do it with the regular version? We have an Exchange server and want spam filtering and greylisting in the front end for one domain. Do I just set in main.cf : relayhost = smtp.server.com
