As for RFC 3834, it's statement:
The primary purpose of the MAIL FROM address is to serve as the
destination for delivery status messages and other automatic
responses.
seems to me to be in 100% agreement with the language of the architecture
draft.
It is, however, not quite correct. At the time that 3834 was
written, there was a second type of "other automatic response"
similar to delivery status, viz. message disposition notifications
(RFCs 2298, 3798). They, however, explicitly use a header
field, Disposition-Notification-To, to specify the destination
for the automatic response. Since 3834, message tracking status
notifications have been added, using a separate protocol for
the tracking status notification. I note that neither MDNs nor
MTSNs are addressed by the draft under discussion.
