note to the ietf list: I suggest we redirect this discussion to
ietf-smtp(_at_)imc(_dot_)org
with a cc to ietf-fax(_at_)imc(_dot_)org rather than to the main ietf list, and
I'm
trying to do that for any further replies I send.
(so if you don't see me replying to this stuff on the ietf list, don't assume
I'm being silent :)
