None of this is surprising, at least to me. The question is
whether you think the SMTP spec should be modified to _require_
servers to accept the sorts of "variations" you outline and to
explicitly authorize (and thereby encourage) clients to send
them? And, if so, which ones and why?
May I ask, what are your plans or considerations for 2821bis?
What new considerations are in it?
