Don't forget that you can have multiple imap folders.

I keep a lot of old emails just in case I need to refer to them later. I use pine, and I've noticed that it gets slower as my inbox gets bigger. It would be unusable if I kept everything in my inbox. To speed things up I create a new imap folder once a month and move my inbox to it, thus cleaning out my inbox.

Maybe you should encourage your users to do something like that. Even if you go to a different imap implementation, having smaller folders might help keep things quick. You could automate the process with scripts that move the folders at scheduled dates, or with scripts that run periodically and warn you about users with exceptionally large folders.
