I haven't had to move mailboxes but the format you describe above sounds
close to what courier IMAP uses. It uses a modified Maildir format,
where other created IMAP folders are stored in files inside the
${local_part}/Maildir directory. It would probably not be that hard to
write a script that reorganized the directories and copied the mail. You
would lose all the flags though, unless you can figure out how messanger
stored them and read them out.
Courier just needs exim to write the new mail to the user Maildir/new
directory once you've migrated the old mail.
