Do I understand this correctly?

	$ORIGIN domain.com.
	server A 123.45.67.89
	www CNAME server
	mail MX 10 ???
	mail CNAME server

If this is what you meant, then it is clearly wrong - any name server
accepting this input should be considered broken, IMO. CNAME is a
singleton type - you can only have one CNAME at a given node, and you
cannot have anything else at that node.

If you meant (plus the other data above):

	@ MX 10 mail
	mail CNAME server

then it's a little better, but not much. Having the LHS of the MX
mention a CNAME might work, but it also might not.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
