Oh dear, there's always a catch. This wouldn't be an issue if encrypted
body content was a thing but all the time that I had active pgp keys and
some savvy correspondents I got, over a few years, maybe a half dozen
encrypted bodies.
I am inclined to think of it this way: can't trust TLS relays at all,
and they're just another relay. At least I can send mail. Am I being
naive?
