I use the following :

;;
;; smime sign/verify messages
;;

;; regexp of groups from which new messages are smime signed by default
(setq my-sign-smime-group-regexp "^mail.work")

;; same, for gpg
(setq my-sign-pgp-group-regexp "^mail.perso")

;; hook to setup message
(defun my-mml-secure-message-sign ()
  (cond 
   ;; smime
   ((string-match my-sign-smime-group-regexp gnus-newsgroup-name)
    (mml-secure-message-sign-smime))

   ;; pgp
   ((string-match my-sign-pgp-group-regexp gnus-newsgroup-name)
    (mml-secure-message-sign-pgp))))

;; plug this into message-setup-hook
(add-hook 'message-setup-hook 'my-mml-secure-message-sign)


Hope this helps.
