I have a secondary domain setup in my exchange environment, only a couple of folks using that domain email.
Got an ndr that says unable to relay for mail.primarydomain.com at x.x.x.x . I have setup mx, A and txt records for the secondary email domain, mail.secondarydomain.com This was done with the help of a consultant who is an exchange specialist, in whom I have a lot of confidence. That being said, I'm wondering if exchange ever really sends mail out using mail.secondarydomain.com?? Can someone enlighten me please? ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
