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.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
