That seems messy. Is there not a way to tell Postfix that if the mail is for local delivery that it should just hand it off to the local delivery engine and not do a DNS lookup to find the mailserver? This is what qmail does. It's running under the same conditions and delivers the mail correctly.
The connection between the local host mail.xyz.com & the domain xyz.com needs to be spelled out for Postfix perhaps?
A further observation on the IP# issue. Apparently Zimbra in the install process does a DNS lookup for the server name and adds an entry in the hosts file with the public IP # of the server. In the situation where the Zimbra server is behind a firewall which will not allow traffice that originates on the internal network back into the internal network (which is common in my expirience) then Zimbra will hang when it tries to start up.
The time outs are so long that I was convince that something had happened to my install & reinstalled the OS. The second time it happened I figured it out & booted Linux in single user mode & shut down the auto startup of Zimbra.
