We have opened a satelite office in Australia and I want our mail server to start accepting mail for: our-domain.com.au.  Here are the steps I have completed so far and the result when I send mail:

I have updated our MX record with the .au domain name (I have checked using MXtoolbox.com, it's quoting the correct IP) and 'pointed' it at the IP address (external) of our Exchange Server.

On the Exchange Server (2007, SP2) I have added an entry in the Accepted Domains which looks like this:

Name                                      Accepted Domain              Type                 Default

Our Aussie Domain                 our-domain.com.au           Authoritative     False

We 'own' the Domain Name in question and have it parked.

When I send a mail to me@our-domain.com.au I get:

Delivery to the following recipient failed permanently:

    myname@our-domain.com.au

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.1.1 User unknown (state 14).

What else do I need to do and what about reverse DNS, is there anything I need to configure in regards to this?
