Hey, Xavier.  I was just responding to Antoine's comment that he had
"trouble making message-mode digest an existing buffer".

As for resuming postponed messages, I have defined the following key
binding, which I use on draft messages that have been indexed by
notmuch:

(define-key notmuch-show-mode-map "R"
  (lambda ()
    "Resume a postponed message."
    (interactive)
    (notmuch-show-view-raw-message)
    (message-mode)))

jamie.
