[Dovecot] Mixing mbox and maildir

[Robert Cooper]

(er...meant to send this to the list....)

One thought, since I'll be doing this conversion once I get my new 
mailserver in place...

Since I've only got 3-4 users, I'm planning to just open IMAP mailboxes 
on both servers in Thunderbird, and drag the messages from the old 
server (using mbox) to the new (using Maildir).  However, It would 
require two boxes, or two IMAP servers running on different ports, and 
would not be sufficient for more than, say, 5-8 users.
