"Proprietary" backend - I'm using Cyrus IMAP, authenticated via LDAP
with Exim delivering messages via LMTP.

My experience is that Maildirs served via IMAP suck when you have more
than a couple hundred messages in a folder, and mboxes have this problem
with multiple login sessions. Neither are a problem with Cyrus.

Indexed maildirs with Dovecot have the potential to not suck, but
Dovecot still has a lot of maturing to do, when compared to Cyrus.

IME there are 2 drawbacks to Cyrus:
 a) It uses SASL for authentication. Black magic and flying rubber
chickens abound!
 b) The *only* ways to access your messages are IMAP and POP3
