Creating a new accepted mail domain for Exchange

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?

it doesn't have anything to do with reverse dns as you are getting a 'User Unknown' error. Do you have any anti-spam service like message labs or anything like that where you need to upload and approve the email addresses ?

Firstly...whoops.  I did have an .au address, but I had made a typo!!  Sent a mail using the correct syntax and it worked!  My question reagrding Reverse DNS was not why was the mail failing (because I can't spell it turns out!), will I need to do anything regarding reverse DNS as part of the setup?

its always best to have a reverse dns set up - as more and more are using it to fight off spam.

Reverse DNS will have to be set up by your ISP as they control the IP address given to you and associated to your account. Once you give them a call, they should be able to sort it out.

I wonder if you have any gateway and preventing mail from gateway only .. you probably need to check the setting on the gate ways first .
