In section 4.8, you mention "A" lookup.  Is AAAA explicitly not done
in that case?


Sorry, I didn't check that reference.

Yes, the exists: mechanism explicitly checks *only* A records, even if
the MTA connection is via IPv6.  This is to maintain compatibility
with already existing DNS blacklists and whitelists.


Any reason not to query for ANY?
