Thank you! Not blacklisted.
Can you tell me where to find the Exchange logs that would have information on why the email is returned?

-greylisting
-server not responding
-incorrect email addres
-You blacklisted somewhere (some servers then use greylisting for your emails)
You could check if the remote server is responding (ping, telnet to port 25), check wether the are greylisting and check if you're not blacklisted (http://mxtoolbox.com/blacklists.aspx)
