"The result of an MX lookup MUST NOT be a CNAME."
Can this *please* be slightly reworded? "The RR value of an MX
lookup..." perhaps?
It is the compound "MX lookup" that generates ambiguity, as it is used to
indicate the initial lookup of the domain name. Actually, that's what the
whole first paragraph in 5.1 is talking about. If it were considered a
minor change, I'd propose moving that sentence to the end of the next
paragraph, where its rationale can be grasped more easily.
