Yes; sorry.

Emacs cannot possibly know that when you send to "arthur", that that
email will eventually end up going to "arthur@gnu.org". It could guess,
but guessing in an security context is a no go.
So if you want to send somebody secure messages, you have to tell Emacs
what address the mail is going to: You can't just say "arthur".
