Yes, well, that's what I said would happen.

With the fact that it /attempted/ to connect to our mail server - not 
localhost, and not yahoo.com.

I see the same behaviour with either getDefaultInstance() or 
getInstance() - it connects to our mail server.

I get:

javax.mail.MessagingException: Unknown SMTP host: zoogz.gregorie.org;
   nested exception is:
         java.net.UnknownHostException: zoogz.gregorie.org

I presume your DNS does not propagate upward from your zone. But it /is/ 
attempting to resolve that hostname via our DNS servers. It's not using 
localhost.
