How is your Zimbra server conected to the Internet? Does it have it's own public IP address, or is it behind a firewall?
My zimbra server is on a internal LAN, IP 192.168.1.7, behind a server with a static IP and with a firewall. I can send(from the LAN) and receive mail(from every other net).
You do have a seperate IP for the main site and for your zimbra server correct? Or are you just using port forwarding on the firewall?
What experience do you have with DNS, you may need to get your hands dirty!
Check that the mail.domain .com address resolves to your own external IP address, I'm going to guess that it currently does not. You will need to make that change first.
I have a public IP to my main server and an private Ip to my zimbra server. In the main server I am using port forwarding (the mail gets in and out ok)
I have little experience with DNS but I have read a lot of tutorials and help pages!!.What experience do you have with DNS, you may need to get your hands dirty!
I have set up a splitdns and zimbra works fine.
When I run nslookup mail.mydomain.com in some machines of the LAN it gives me my external IP address, but if I run it on my main server or in some other machines it gives me the local zimbra server ip address.Check that the mail.domain .com address resolves to your own external IP address

It seems there is some problem with your DNS.Have you checked DNS properly.Ping your mail server and xhexk it should get resolve to your public IP.
