Subject: [PATCH 1/4] test: initial tests for smime

Precedence: list

Test the ability of notmuch-mua-mail to send smime signed messages;
this really relies on existing functionality in message-mode.

The dependency on openssl to generate keys seems acceptable since
that's the method I got to work for smime signing in emacs.
