Thanks for reading.

I am unable to receive mail on a new setup.

Either externally or internally. Though I actually think the source is two seperate issues.

I have all of the local ips for this server in the trusted MTA section.

I have now disabled 'Enable DNS lookup' and set my zimbra server to relay mail for this server. I would like a fix that does not use a relay server though.

Here is a tail from /var/log/zimbra.log, that I think will help with the local issue

Here is a log tail that I think shows to external issue
