	The simple response is that there's no way to determine definitively where
the mail is supposed to go. 'supercom.ca' is a great example. There is no
way to determine where mail to that domain is supposed to go, and it's much
better that it not work than simply guess.

	Let me put this question another way: How can you tell the difference
between a 'permanently' misconfigured site and one with a transient error?
Do you want mail to be sent to the wrong place because of transient errors?
