Uses Python's included mailbox library to convert mail archives from
maildir [http://en.wikipedia.org/wiki/Maildir] to
mbox [http://en.wikipedia.org/wiki/Mbox] format.
See http://docs.python.org/library/mailbox.html#mailbox.Mailbox for
full documentation on this library.
---
To run, save as maildir2mbox.py and run:
$ python maildir2mbox.py [maildir_path] [mbox_filename]
[maildir_path] should be the the path to the actual maildir (containing new, cur, tmp);
[mbox_filename] will be newly created.

import mailbox
import sys
import email
# open the existing maildir and the target mbox file
maildir = mailbox.Maildir(sys.argv [-2], email.message_from_file)
mbox = mailbox.mbox(sys.argv[-1])
# lock the mbox
mbox.lock()
# iterate over messages in the maildir and add to the mbox
for msg in maildir:
mbox.add(msg)
# close and unlock
mbox.close()
maildir.close()
