I am trying to setup iRedMail and am way over my head here. I have installed it, and can send emails internally, but not externally. When I send an email from outside, I get the following return email:

The error that the other server returned was: 550 550 5.7.1    
<[email protected]>... Relaying denied (state 13).

Now I have no idea where to start looking! Any ideas? I have really only just installed iRedMail so I am unsure what else I need to do to get it working. I've pointed my MX records to that server, so that shouldnt be the problem.

Also- if i stop postfix (so nothing is listening on port 25) and send a test email, I get the same reply back. Why would I get the same reply back even if postfix is stopped? I have run tcpdump over 25 and can see the packets coming in/out, so its definitely a configuration issue!

I suppose my question is not really "what is my problem", but more "What configuration needs to be completed on postfix and iRedMail?"
