As I read it, the "verification" that MUST NOT is talking about is the
verification the previous sentence mentions, and that's a check I don't
do - and thus that's a MUST NOT I am not in violation of.  Your HELO
can claim you are any existing host on the net, and I won't mind - but
claim a nonexistent (or nonsyntactic) name and I'll refuse it.

Unless DRUMS has something in draft that clarifies that the MUST NOT is
to be read as you imply it should, in which case I'd much appreciate a
