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?"
