Thanks for the quick response Noel. Ok, so what you are suggesting is that I've setup the mail server to be mail.mydomain.com at ip x.x.x.y When smtp2.scudc.scu.edu checks x.x.x.y it gets adsl.blah.pacbell.net and thus rejects?
What do I need to do to get it running? Why does it 'eat up' the error message? I'm getting similar problems with sbcglobal.net addresses but at least I get an error message from postmaster.... Hammad. p.s. I'm new to the world of mail servers.... -----Original Message----- From: Noel J.

They are probably doing a reverse DNS lookup, and getting a failure. --- Noel --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
