Cyrus 2.3 CVS code enables you to split indexes and cyrus db files into
their own partition. That's where most of the i/o activity is concentrated,
so you only need to optimize that partition. The mail spool that remains can
be raid5.

Yes, ext3 does have its problems, depending on how many users and how big
mailboxes you have. I'd recommend reiserfs.
