I'm running Windows SBS 2003 SP2 with Exchange. Recently, we got ourselves into trouble with a few blacklists due to relay settings and authentication settings. I tightened up these after reading numerous articles on the subjects and have removed us from these blacklists. We've stayed oof of them for about two weeks now, but I am still unable to send emails to AOL, Yahoo and a few other private email servers. Our mail domain is registered under a certain ip address, but when our mail goes through, I noticed that it is recieved from the servers ip address, which has no DNS stetup. I need our email to go through the server which has the DNS setup for our domain, but cannot figure out what to configure in the System Manager to do this. I know it was setup at some point, and I believe it was changed sometime within the last couple years. Any ideas/explanations?
