hmmmm, actually I think I may have jumped to conclusions on this one PsiCop.
This does appear to be a error message "from" the receiving server and not a send error.
This could also be related to a Reverse DNS validation issue (missing PTR record)

Recipient address rejected: Domain not found
-----------------
The answer to your problem is:
-->Recipient address rejected: Domain not found<--
It apears the message was sent to a invalid domain or one that your mail server couldn't identify. Check for typo's. It's also possible that the network your mail server is on could have been experiencing problems.
