Private-communication authentication
The thing about certificates though is that they're about (1) one party authenticating they are who they say they are, and (2) the same party authenticating that the connection is secure.

Email doesn't work that way...and from time to time you're going to get unfamiliar senders (and, therefore, non-whitelisted senders) who are sending legitimate email.

Of course, all of these emails could be "authenticated," but then what if someone who has authentication via a certificate authority then decides to become a bad actor?

The easy rebuttal to this is that, "Well, that's okay, because we'll have their identity -- and can thereby revoke their authentication."

But then that gets us down the data-privacy rabbit hole.

It's one thing for online retailers and other sellers / companies to authenticate themselves publicly.  It's another thing to ask people to authenticate themselves for private communication.

Or what am I missing here?

Email authentication
Thank you for the post. As a user, would be great to know that emails that I receive are coming from authentic sources. Hope DMARC or something equivalent can be sufficiently prevelant that non-DMARC mails can directly go to my spam folder!
