A client has an internal Apple Server setup in their office that manages their domain (let's say it is example.com).
I have setup a subdomain of example.com (test.example.com) on Google Apps as I want to use email addresses under test.example.com 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 email@example.com.
For some reason the Apple server seems to be saying - "I am setup to manage example.com and hence all subdomains of it. I have looked - but I cannot find a subdomain of test.example.com - so the email is undeliverable".
How can I get the apple server to ignore test.example.com and all of its email?
