I'm new to Zimbra. I appreciate the help and please have patience!

I've setup Zimbra a FC4 box. The Zimbra server sits behind a router performing nat and FW functions. So the external address that mail is sent to is different from the IP address of the Zimbra server. That appeared to be a probelm during install, so I configured BIND on the server with Zimbra. This allows Zimbra and LDAP to resolve both the server names and the MX record to the actual IP of the server. This IP btw is 192.168.1.220.

The hostname of the server is server1.mydomain.com. Mail MX record is mail.mydomain.com. I have an alias setup in DNS to point the MX record to the A record for server1.mydomain.com.

[zimbra@server1 /]$ host server1
server1.mydomain.com has address 192.168.1.220
[zimbra@server1 /]$ host mail
mail.mydomain.com is an alias for server1.mydomain.com.
server1mydomain.com has address 192.168.1.220


Output of some commands (all run as user zimbra):
[zimbra@server1 /]$ zmcontrol start

When I receive mail, which I never acutally receive, I get the following:

FYI, mydomain.com is a substitute for my acutaly domain.

Thanks for the help and let me know what else you need. You may need to specific, like what commands I need to perform to get you the information.
