A client has an internal Apple Server setup in their office that manages their domain (let's say it is

I have setup a subdomain of ( on Google Apps as I want to use email addresses under for an app that I am building. The reasons for needing GMail aren't important - but I need it.

The problem arises when someone from their office tries to email

For some reason the Apple server seems to be saying - "I am setup to manage and hence all subdomains of it. I have looked - but I cannot find a subdomain of - so the email is undeliverable".

How can I get the apple server to ignore and all of its email?

This question came from our site for professional and enthusiast programmers.

If the server's configured as authoritative for, it's authoritative for everything under, too - working as designed.

Sounds like you're saying they have separate DNS records out on the internet that they want to be used for the lookups? Then their internal server needs to have NS record(s) delegating to those remote devices.

You're basically running a split-brain setup. There's no way to "exclude" DNS subdomains for a zone that you are running on; any subdomain of will be covered by your local DNS. So instead, you should manually add the DNS entries for Google Apps into your Mac Server.

So take a look at the client's external DNS entries, and basically copy all of the mail-related ones into the Mac server. Internal clients will then recieve the proper information from the internal DNS.
