[rt-users] Postfix + RT3 Guide

[Josiah Ritchie]

I've played around a lot and think I've managed to apply everything you
mentioned here. It looks like I'm getting further. I'm not getting the message
bounced with the message: "550 Relay denied" from the exchange server. I'm not
sure if it is getting this from postfix or if It's simply saying Exchange won't
do it. I'm assuming Exchange is the problem. I think I told it to relay for my
hosts, but not sure. Anyway, I'm still looking into that possibility and
wanted to just mention that I'm getting closer.

Any tips on things to check in the postfix main.cf that might cause this?

Maybe I need to setup an MX record on my AD server...
