New Installation - Will not recieve mail???
Outgoing email is fine. This is an Ubuntu server with newest Zimbra version. The server is behind a firewall and a Split-DNS is being used. The firewall has the server in a 1:1 NAT. This is a new domain and I'm not sure if it is configured correctly. I followed the Beginner's Guide to installing Zimbra on Ubuntu 6.06 Server instructions. They worked fine in the past.
I've looked at Incoming Mail Problems - ZimbraWiki and all seems to check out. I even scanned my ports to check the correct ones are open. All of them check out.
My server is mail.berrienhospital.com. Any suggestions?
