I am running Exchange 2K3 on a Windows 2K3 server and whilst i can send mail to almost anyone without a problem i keep getting blocked by spamlab .com for having an open relay. the following is the open relay test done at this site. I need assistance to figure out where in Exchange to close the gaps identified.

Thank you, I checked this site against what we have setup and everything they indicated to block spam is setup in Exchange. My concern is the 3 tests below since everything else they tried is blocked.

Some systems appear to accept relay mail, but then reject messages internally rather than delivering them, you need to use a test that actually sends you a message, like http://www.abuse.net/cgi-bin/relaytest
