I am currently using Cyrus IMAPd, and been using it for a long time, the main reason being that I want an IMAP server with nice server-side filtering, which Cyrus provides via Sieve. Given that Sieve is integrated with Squirrelmail, all is good.
have you tried Dovecot? it seems a lot simpler and easier to setup and manage than Cyrus. I believe it has optional database integration. Dovecot also supports Sieve, also, although I've never used this, http://wiki.dovecot.org/LDA/Sieve
Dovecot also is bundled with CentOS 4 and later, I dunno about CentOS 3.
