;; Commentary:
;;
;; This is the beginning of a solution for storing sent mail in a
;; maildir in emacs message mode, presented because some people might
;; find it useful. It is *not* fully tested, it *may* overwrite files,
;; and any directories you point this at may no longer be there
;; afterwards. Use at your own risk.
;;
;; To use this as the fcc handler for message-mode, put
;; one of the following in your init file:
;;
;; if you want Fcc'd messages to be marked as read:
;;
;; (setq message-fcc-handler-function
;; '(lambda (destdir)
;; (jkr/maildir-write-buffer-to-maildir destdir t)))
;;
;; if you want Fcc'd messages to be marked as new:
;;
;; (setq message-fcc-handler-function
;; '(lambda (destdir)
;; (jkr/maildir-write-buffer-to-maildir destdir nil)))
