	Because it is not legal and never worked the way you thought
	it did.  If you actually look at the log from 4.9.6 you
	will see it complaining as well.  It's just that it is a hard
	error now.

	CNAME is a record that says "the real name for this domain
	is ... and look there for the data".  In the example above
	the MX record should be associated with morgank not emc.
