I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

DNS Problem.  It means that there is no DNS server that can resolve this email address.

If you are sending over Smart host check this, or check your DNS Settings (DNS Forwarders and clear DNS cache).
