	I am aware that the low level protocol doesn't matter squat
	and it shouldn't, that's part of the reason behind all this
	stuff! See next paragraph.

	Yes, I know. The trouble is it WON'T try to talk to the
	exchanger, it wants to talk to the non-networked site. B^(.

	I guess I should clearify. I'll use REAL site names. Say I
	want to mail to joe@bungia.mn.org. a.cs.uiuc.edu HAS an MX
	record for mn.org and thus can be used as a gateway to it.
	HOW do I tell sendmail it should contact a.cs.uiuc.edu rather
	than bungia.mn.org. bungia.mn.org is a CORRECT canonical name
	it just doesn't have an SMTP connection. CAN sendmail find out
	that a.cs.uiuc.edu is the mail exchanger for bungia.mn.org and, finding
	that out, can it talk to a.cs.uiuc.edu rather than sending out a connect
	request to bungia.mn.org, a site that isn't directly on the net.

	Right now, no matter what I try, sendmail wants to talk to the
	non-networked site, NOT the mail exchanger. How do I get sendmail
	to talk to the right machine?

	I thank Mr. Zeilenga for his comments and hope that my clearification
	explains better the question I was asking.
