I have a client who is running Symantec Mail Security for Microsoft Exchangeon Windows 2003 Server. Up until about 2:30pm today, mail from my domain was able to be delivered to their domain, no problem at all. After 2:30pm, our mail is being bounced back as being rejected as spam. Symantec Mail Security for Microsoft Exchange is the only mail spam software they are running, and after stopping the Symantec Mail Security for Microsoft Exchange service, our emails could get to them. As I know just about nothing of the Symantec Mail Security for Microsoft Exchange software, where would I find a listing of good/bad domain names or such? White/Black lists in the program?
