There was a very helpful url posted on one of the redhat lists a couple of days ago: <http://people.redhat.com/rkeech/maildir-migration.txt> It seems that RHEL4 (I think fedora already) are moving to dovecot as their IMAP server, so that may be a direction you want to go. As someone else said, mbox is probably your problem. This page also has info about why mbox is bad with large mail folders and how to convert to maildir. I've only been working with dovecot a couple of weeks, but it's ok so far. Courier IMAP has also worked well for me in the past (with maildirs) but I had some problems building on my x86_64 system and dovecot ended up being my path of least resistence. Jason (I think) pointed out to me that you can build rpm's from the courier imap tarball pretty easily (see the courier faq) and that was pretty cool. Probably best to stay with SquirrelMail and I don't know much about the other groupware stuff.
