;; MUA specific functions for mu4e
;;
;; Setup with (add-hook 'mu4e-main-mode-hook #'autocrypt-mode)

;;; Code:

(declare-function mu4e-view-raw-message "mu4e" () )

;;; XXX: mu4e seems to share no common mode, and the `derived-mode'
;;;       specializer supports only one mode (currently). Therefore
;;;       the method definitions have to be duplicated.

;;;###autoload

  (require 'autocrypt-mu4e))
