I have been doing some reviewing of myself and intend to publish on privacytools.io early next year.
https://github.com/privacytoolsIO/privacytools.io/issues/603...
I tested a number of new email and security related RFC to see how the providers complied. We plan to have a criteria (also in that issue) to rate them on a scoreboard.
I'm also hoping some of these providers will really consider
• https://jmap.io/
• http://arc-spec.org/
Despite what some people say, I think email will always exist in one form or another. There is a need to send a simple text message to people with minimal fuss. That means no walled gardens or bullshit to get in the way.
