Downstream policy is to follow our recommendation to the letter.

If we want to keep this desktop file, we should make it a configurable option, default off. If on, Emacs mail should use sendmail by default.

It is hard to think of circumstances where it would work as expected nowadays. Typically, If you are able to send mail, you are a known MX, and if you are a MX, you do not have interactive users. But maybe on some isolated intranet.

Maybe the emacs-mail.desktop file as included in the Emacs release
tarballs should have some prominent comment in it warning about this
issue?
