Good. If you can reproduce a consistent issue, please let Sun know.
Personally it sounds as if your DNS server has some issues, if you are
getting such inconsistent replies.

James. But JavaMail is the one looking up the server address, and throwing
the UHE.

If there are multiple servers, James will try them each in sequence. There
were some recent changes to improve that behavior.

If there are multiple MX records, you should see James try the next one
immediately. I have seen that often enough with Hotmail, Yahoo!, AOL, etc.
