Implicit in the above statement, but not actually formed as a question, is
the possibility of changing MTAs: DON'T DO IT.  Courier rocks for certain
things (eg. IMAP), but as an MTA, it kinda sucks.  The author (whose name
escapes me at the moment) has an almost religious adherance to RFCs, which
makes for some unpleasantness when non-conforming e-mails come 'round. 
I've used Courier-IMAP successfully with both Exim and Qmail, and would be
glad to dig up an Exim config file for you if I still have it around...

Courier's decent.  I enjoy it.

Yes, it does.  Whether or not there's a way around it (a patch, or
what-have-you) I don't know.  However, let me just say that maildir really
is superior -- it makes a lot of things a lot easier to do.  Depending on
how many mailboxes you have to convert, it can be relatively easy, and I
bet a script wouldn't be too difficult to implement.

Fire away; I promise no guruship, but I've used Courier IMAP for the past
year or so in a mid-sized production environment.
