I imagine that you would include SPF and DKIM in this list.
Would you include DMARC, and the new list-friendly version, of which I know
My strong preference would be to include none of these, and only SMTP
and MIME specifications.
I agree. DKIM and SPF sit on top of SMTP and are not part of it. DMARC
and ARC are even more sitting on top and are less part of it.
