Those are a concern of Notmuch and MSTMP only. If Emacs is generating the Message-ID, I'd say Emacs needs enough information to do so - the recommended way is to put the host after the @.

(The whole purpose of the Message-ID is to uniquely identify the message! I guess you mean identifying... the sender? But that's also done in From:, right? If you are thinking of identifying the machine sending, then that is recorded in the Received headers as well, right?) > Whenever I use Emacs from a device where the hostname returns a fully > qualified name like an IP address, that will leak into my Message-ID.

Not except for what RFC 2822 recommends: · https://tools.ietf.org/html/rfc2822#section-3.6.4 At least according to the logic in the RFC, you should put something you control on the right side of the @, and not somebody else's host/domain - but as long as the whole thing is unique, you should be good.
