I use a python script :)
This python script is called by procmail, a mail filtering program (Linux).
The first argument is the file in which it should be redirected, the input
is the e-mail message. It reads the e-mail, checks the DATE header and
throws the e-mail into the mailbox for this week. Every week, I start a new

#!/usr/bin/env python

"""Appends email message from standard input to mailbox argv[1] in the correct date"""

import os
import sys
import email
import email.Utils
import time

MAILDIR = "/home/gerrit/email"

def getdestfromdate(d):
    timetuple = email.Utils.parsedate(d)
    print d, "=>", timetuple
    timetuple = time.localtime(time.mktime(timetuple))
    subfile = sys.argv[1]
    jaar = time.strftime("%Y", timetuple)
    week = time.strftime("%U", timetuple)
    dest = os.path.join(MAILDIR, jaar, week, subfile)
    return dest

def main():
    message = email.message_from_file(sys.stdin)
    dest = getdestfromdate(message["Date"])
    print "Appending to", dest
    if not os.path.exists(os.path.dirname(dest)):
        print "creating dir for", dest
    fp = open(dest, "a")

if __name__ == "__main__":

Note that this may not run with Python prior to 2.3.
