It seems to still exist -- draft-danisch-dns-rr-smtp-03 is dated 2003-10
-- though it should have been abandoned long ago in favour of similar but
superior proposals.  draft-fecyk-dmp (formerly draft-fecyk-dsprotocol),
which has almost identical capabilities, is also still in active
development.  There's also a more flexible version of the idea, which
I skimmed through when it was announced and now can't recall the name of.
