Investigate a switch to Cyrus. I was up against the same things with Courier (a few thousand users, about 2 million emails) and I believe it comes down to the architecture of the software. Don't get me wrong, I love courier and still run it in smaller installations, but nothing beats Cyrus' indexing for high-volume IMAP servers. > This increased a bit the performance but not in such a miracle way.

It's the FreeBSD version, so UFS might be sufficient.

PHP's not the problem here, it's your IMAP server (or *maybe* filesystem/disks). I'd setup cyrus and migrate a couple mailboxes over to see if you notice any improved performance metrics.
