If your Imail server is behind a firewall (as mine is), then I think you may have configured it incorrectly. The TCP/IP address entered on my Imail server is its internal IP address. All of my internal users and any services on the Imail machine use this address to talk to this machine. Very efficient because the firewall doesn't have to be involved and we use direct ethernet-ethernet routing. My firewall forwards packets directed at the outside email IP address to the internal IP address, and changes the source IP address of packets sent from the Imail server to its external address. All the other internal machines use standard NAT so they all appear to be coming from the firewall external IP address. I've got an internal DNS server (which the firewall provides) that translates the name of my Imail server to its internal IP address. My ISP hosts my external DNS entries. If you run your own DNS servers, they can probably be configured to provide this feature. If you have your Imail server in a DMZ, then its slightly more complicated to configure but the same principles apply.
