The following may be of interest to you. I hacked it up for my own
use.

I would suggest that you save the value of the mh-folder-list as it
may take some time generate. Only do the my-mh-make-big-folder-list
when you need the list updated.

(defun my-mh-make-big-folder-list ()
  "Return a list of the user's folders.
Result is in a form suitable for completing read."
  (interactive)
  (message "Collecting folder names...")
  (save-window-excursion
    (mh-exec-cmd-quiet " *mh-temp*" "folders" "-fast" "-recurse")
    (goto-char (point-min))
    (let ((list nil))
      (while (not (eobp))
	(let ((start (point))
	      (count 0))
	  (search-forward "\n" nil t)
	  (let ((folder (buffer-substring start (- (point) 1))))
	    (mh-push (list (format "+%s" folder)) list))))
      (message "Collecting folder names...done")
      list)))

(setq mh-folder-list (my-mh-make-big-folder-list))

Enjoy!
