No, I left the mailboxes as mbox and did not convert to maildir.  I had
all sorts of mail clients and some use direct file access to their
mailbox, so it requires a lot more deep-think before I can contemplate
moving to maildir.

Many people on this list have successfuly migrated to maildir so I don't
think you'll have too much trouble.

You'll appreciate that dovecot avoids some of the problems I had with
qpopper:

 	- qpopper made temp copies of a user's INBOX, and if you didn't put
 	the drop copy on another filesytem, you essentially halved a user's
 	quota.
 	- because of the above, qpopper eats I/O like candy.
 	- multiple client qoppper access will trouncing/locking user INBOXs.
