Yes:

I have an issue with my smtp virtual server. I'm running W2K3. The issue is I can send out email fine to domains that I have set up in DNS fine. However, when I try to send email out to other domains, I get an NDR with a message in my events log as the fo
llowing...replace somewhere.com with any domain.

Message delivery to the remote domain 'somewhere.com' failed for the following reason: Unable to deliver the message because the destination address was misconfigured as a mail loop.

It's looks like it's not relaying.

I have my MX record pointing to the mail server ip address.

Any help would be appreciated. Thanks
