"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Can you specify exactly where I should check Annonymous Authentication? I may have it wrong.

Check your mx record from it sounds like it is not pointing at the external IP address of your router/firewall
That is checked by default on the SMTP connector in 2003 but not on a recieve connector for 2007.
Is the external IP address of your router/firewall?
Is this SBS2003? Have you added to your email address policies? Have you ticked the box to sayExchange is responsible for delivery to that domain?

The MX record is correct. Points to our public IP.
How do I add to the policies so that the server accepts mail sent to And how do I make my new server responsible for handling mail?
