Great, thanks!

We just moved a large cluster (100k+ active accounts) from courier
pop/imap to dovecot (v1.0.0), and used the courier-dovecot-migrate.pl
to do the conversion of maildirs.

A couple of other failures we've been hitting is:

The "deliver" bugs are quite bad, as they lead to incoming messages
getting bounced..
