We use Bill Shupp's toaster. Would anyone know whether Dovecot is an easy
replacement for Courier?

I have to second, third, and fourth that. We moved from Courier to
Dovecot and the performance change was dramatic. We have 5,000+ accounts
on 2 clustered (active / active) servers utilizing GFS for the file system
on a SAS SAN and the fact that Dovecot had built in support for clustered
setups was a major plus. Had a few issues off the bat with POP3 UID's but
quickly fixed that one thanks to Dovecots easy to change UID
definitions. Don't think I'll ever change back.

Dovecot has really come out in the past year or so. I started with .99,
I upgraded from Courier, but honestly it wasn't really up to date.
Dovecot's indexing showed an immediate improvement on large mailboxes.
With 1.0.5, the only issue I have is with a few older Mac clients. For
me this affects about 4 out of 450 clients total.
I don't have any numbers, but I've had at least 1500 messages in my
INBOX, not including subfolders, with great performance. The change was
so dramatic I didn't need any numbers.
