I've created a brand new, completely functional Active Directory for a client. They've decided to do away with their existing Exchange 5.5 box in favor of a new 2003 server. It houses all mailboxes and public folders. The only problem that I am currently having is that it relies on the old server as its internet mail connector. How do I go about removing the Internet mail service from the exchange 5.5 computer and have the new one receive via DNS. There are no static routes to a mail server on any border devices pointing to either machine.
