I would say it is a great IMAP/POP server for almost any site.
Best would be to wait for the release version of course, but most
(not all) of the RC releases are stable.

Report them individually to the mailing list, and you will get instructions
on how to debug/repor them...

We use mbox format and have no problems, though our largest mailboxe
is 600 MB, so I have no idea how this would work with a 1.1 GB mailbox.
I'd be sure you have lots of memory in the machine if you want to be
handling mailboxes that size.

We use sendmail for MTA, procmail for filters, dovecot for pop3/imap,
Horde/IMP for webmail, and have no problems.  You don't have to move
to maildir, or sieve, or anything else.  dovecot plays nice with almost
any software...
