[Dovecot] Are you using dovecot in production?

We're looking at moving to dovecot from courier, and I'd like to know
what sort of use dovecot has in use on production mail systems.

We're a small ISP and have about 10,000 mail users. If anyone on
this list is using dovecot in a similar environment please drop me a
line privately.

Also have anyone successfully compiled 1.0alpha5 on Mac OS X? I
haven't heard from anyone on my previous email, which makes me a
little nervous.
