Package: notmuch-emacs
Version: 0.18.1-1
Severity: normal

Thanks for notmuch-emacs!

When sending mail from notmuch-emacs interface, I usually use pgpmine
signatures, but sometimes I want to send a signed encrypted message, so
I manually edit the mode=sign to mode=signencrypt ... but if I make a
typo, i.e. mode=signinvalidencrypt, notmuch happily and without warning
sends the mail unencrypted.

i.e. #secure method=pgpmime mode=signinvalidencrypt will end up
sending an encrypted message (with the <>, of course).

It seems like it should error out if the mode= is set to an invalid or
unknown value, rather than sending mail in the clear.

I've got this set up in ~/.emacs, not sure what all else might be coming
into play:

 '(message-setup-hook (quote (mml-secure-message-sign)))
 '(notmuch-crypto-process-mime t)


live well,
  vagrant
