Yeah, but this is Microsoft's OWN server farm we are talking about here, 
not some small podunk IIS-based hosting provider.

...well, you may be right.  I am probably giving MS too much credit here.

On another note, someone pointed out to me off-list that I apparently 
tyop'd "hostmaster" when I sent the e-mail to MS.  I have since re-sent 
it to the properly-spelled address and again promptly received a "User 
unknown" bounceback.
