This is 100 percent the case, and why these things are this way.

If you wanted to make email two point oh, I dont think it would look a lot like what we have today.

But gmail accepts emails without message-id on personal mailboxes apparently.

I think a mail 2.0 would be notify and pull based.... you notify a recipient's mail server that there's a message from <address> for them, then that server connects to the MX of record for the domain of <address> and retrieves <message-id> message.

Would this make mass emails and spam harder, absolutely. Would it be a huge burden for actual communications with people, not so much. From there actual white/black listing processes would work all that much better.

Is the idea that you could decide from the envelope whether you want to even bother fetching the message? Besides that I'm not sure I see the advantage

jmap is the communication between a mail client and shared directory/mail services on a server. It does not include server to server communications (that I am aware of) for sending mail to other users/servers.
