There's a message-send-hook, which we should probably use. Something
like:

  (add-hook 'message-send-hook 'notmuch-always-bcc-sender)
  (defun notmuch-always-bcc-sender ()
    (message-add-header (concat "Bcc: "
                                (message-fetch-field "From"))))

Though I've just scrabbled this together from the docs, I think it
should work (haven't tried it though).
