-  Sometimes it is good to let the world know which email client you use, so others know which quirks to expect. And it is no shame to let others know that you are way ahead of mail2.0. Notmuch is mail3.0 (at least)!

-  [This mail](http://mid.gmane.org/87y6gtnkch.fsf@SSpaeth.de) (id:87y6gtnkch.fsf@SSpaeth.de) posted the below code, that -when inserted in your .emacs file- will add a User-Agent header (which is hidden during composing and in notmuch show, but which can be seen when viewing all headers of a mail). The header will looke like this:
-  `User-Agent: notmuch version 0.1-92-g3893a9a (Emacs 23.1.1/x86_64-pc-linux-gnu)`
