Definitely stay with your MTA. Courier is annoying pendantic as a MTA.

A fair very short, quick reference to converting mbox to maildir is:
	http://www.cs.utk.edu/~help/mail/convert_old_mail.php

I've used several different scripts. mb2md works pretty well and can 
handle a set of mboxes and folders. mbox2maildir is ok for single 
mboxes. For that matter, formail can do it, though I only have used it 
for undelivered /var/spool/mail/XXX mboxes.

I've had some problems with duplicated messages using the mb2md script. 
As a one line shell script cleans them up, I find mb2md adequate for 
most of my needs.

If you have to convert local mail stores (Netscape, Outlook, etc.) it 
can get more complicated. The best success I've had in those cases is to 
have the user create the folders in the imap email client and move the 
messages from the local folders to the imap folders.

Of course, that is tedious and time consuming for the user, so I've had 
to convert Outlook dbx/mbx to mbox and thence to maildir. (I haven't 
found a tool to do it in one step.) Netscape is not quite mbox format, 
but formail -ds <X >>Y can fix it usually.

Maildir only (as others have already answered)

I've been using it for a few years, though I just started using it 
heavily this last 6 months. Ask away.
