The I-D says:
Generally, the handling of the Author: header field
needs to receive scrutiny and care comparable to that given to the
From: header field.
If receivers lookup the Author: domain too, they can evaluate authentication
and alignment also with respect to that domain. The evaluation may take into
account snd tags, and/or dkim-transforms, or whatever other MLM solution we'll
invent. That is to be done in case From: and Sender: domains coincide. The
result of evaluating the Author: domain may or may not affect the destiny of
the message, but it should be part of the aggregate report. That way, when a
MLM receives records saying that Author: domains authenticate all right, it can
stop rewriting From:.
