Hmm..yes, that would seem more appropriate.

That's an excellent way to put it. Whatever we do, we should not be in
conflict with other methods.
Also, I think we mentioned the possibility of doing C/R on the SMTP server
level but dropped it. We might want to consider it again in conjunction
with the CRI proposal. Perhaps we should specify an SMTP extension that can
do C/R over SMTP. This would save time in some instances (see RFC 1869 for
ESTMP). This way people would have a choice of doing C/R either over email
or over SMTP.
