OK by me.
Hm, it is a border case, why not just say "MUST either
check [2821bis] or as minimal approximation [nxdomain]".
If you really like MAY better I think "MAY instead" is
clearer than only "MUST [nxdomain], and MAY [2821bis]".
If 2821bis is only a MAY you can't rename the result to
"nomailfqdn", it has to stay as is (= "nxdomain"), and
we can close that part of #1579, "not more applicable".
I'd like to suggest that since the how seems to be controversial we punt on
that and just say the ADSP only applies to domains that exist. I think we
perhaps we can leave how to determine this as an implementation detail. The
last 1% of agreement/interoperability isn't worth it.
