When it comes to SMTP for email, time has only served to highlight its inadequacy.

DMAC, DKIM, SPF, S/MIME, PGP are all ugly workarounds. The issues are fundamental.

those ugly workarounds are actually brilliant signs of adaptability (not signs of failure). SMTP isn't inadequate, it's resilient. There's a good chance we'll still have SMTP around another 50-500 years.

		No, we won't w/o breaking changes. There's no way. Even ignoring pressing issues like lack of mandatory E2EE, SMTP requires encoding binary data into text. This includes the main body for most emails these days. Awfully wasteful. So it will go the way of FTP.
