Interesting, I have a similar script that also requires cron/shell  
access to mail server, but works with mbox format instead of MH, and  
is compatible with, e.g., dovecot IMAP server.  Mine is slightly less  
fancy, in that I file messages to absolute folders named "days/25" or  
"months/07-July" (rather than "nextweek") to have them dumped back  
into my spool at the indicated time.  See the 'email-tickler-update'  
script attached.


More relevant to org-mode, I have an emacs-lisp/apple-script combo for  
pasting links to Apple Mail messages into org files:

(defun cal-grab-mail-links ()
   (interactive)
   (call-process "/usr/bin/osascript" nil t nil
                 "/home/league/Library/Scripts/Applications/Mail/Copy  
Message for OrgMode.scpt")
   (yank))
(define-key org-mode-map "\C-cm" 'cal-grab-mail-links)

;;;;; and the .scpt component:

-- Replace all occurences of one string for another in a text
-- The trick here is to change the internal delimiter,
-- spliting and joining the text
--
on replaceString(theText, oldString, newString)
	set AppleScript's text item delimiters to oldString
	set tempList to every text item of theText
	set AppleScript's text item delimiters to newString
	set theText to the tempList as string
	set AppleScript's text item delimiters to ""
	return theText
end replaceString

tell application "Mail"
	set _sel to get selection
	set _links to {}
	repeat with _msg in _sel
		set _subj to _msg's subject
		set _subj to my replaceString(_subj, "[", "(")
		set _subj to my replaceString(_subj, "]", ")")
		set _messageURL to "[[message://%3c" & _msg's message id & "%3e][" &  
_subj & "]]"
		set end of _links to _messageURL
	end repeat
	set AppleScript's text item delimiters to return
	set the clipboard to (_links as string)
end tell
