I did not suggest a discussion of DMARK or DKIM. I suggested that they be mentioned.
Donald,
SMTP is a protocol specification. The document already attempts
to go far beyond it's scope for handling one submission and
direct, associated deliveries. It has quite a bit of text that
seeks to be an general architecture document, as well as trying to
cover activities outside of Internet Mail, per se. It does these
added jobs only partially, at best. There are historical reasons
given, for not removing those bits of text, but it certainly does
not justify adding more material that is best classed as a layer
violation.
DMARC, DKIM and SPF are all completely outside of the email transport protocol specification. They are very much IN scope for a broader discussion of email as a service. But that's a different goal.
