Do you have to specify the domain of a gateway to an email server (exchange 2003). I just recently updated from Symantec Brightmail on Windows 2000 to Symantec brightmail 9.0.2 on Linux. I have all the same Ips set up to deliver the mail. However there's two items that are different. The domain of the Gateway and also linux has somthing called a "broadcast" ip, not sure what that is. Where would i change on Windows 2003, exchange 2003 where it should be getting its filtered mail from?
