I rigged this up for gnus:
;;Be sure we are very aware of Disposition-Notification requests
;;though we can only respond manually at present.
(add-hook
 'gnus-startup-hook
 '(lambda ()
    (require 'gnus-art)
    (setq gnus-visible-headers
	  (concat "^Disposition-Notification-To:\\|"
		  gnus-visible-headers))
    (setq gnus-header-face-alist
	  (cons '("Disposition-Notification-To:"
		  gnus-summary-cancelled ;vivid
		  gnus-summary-cancelled)
		gnus-header-face-alist))))
