Not at all. MUAs shouldn't just *display* the results of A-R as an
indication of goodness/badness of the sender. However, it can certainly
process the A-R information and *combine* it with reputation and/or
accreditation information in order to generate something that CAN be
displayed to the end user.
Ok, well then we don't agree. The information simply cannot be trusted
unless it's signed, and if it's signed there will be agents that can't
verify it. I can tell you that I would encourage administrators to
strip it at the border because of the risk of misinterpretation and
spoofing. This having been said, the wording used in Section 3.1 is
close. I would make the first two SHOULD NOTs MUST NOTs.
