I meant what happens when you query the BIND server directly,
not what happens when you just use MS DNS. It should be fairly
easy to simulate the forwarded query with dig.
If the BIND server answers a normal "dig @... ssl.berkeley.edu
mx" with a non-serv fail answer, the problem is either the
firewall or the MS DNS server.
I wouldn't trust anyone to report the history of their own
servers unless under stringent version control, myself included!
Assume anything might have changed.
