I run a large (>>25000) free email service. We started out with qpopper, but quickly had to switch because qpopper does (or at least did at the time) very poorly with large mailboxes. If the mailbox was very large, qpopper would crash leaving the mailbox twice as big as it was before.
We were using sendmail at the time, so we started using qmail as the local delivery agent. And pop agent of course. Eventually we switched entirely to qmail.
One thing to watch out for regardless which solution you use is that (last time I looked) linux (or is it ext2?) is limited to 16-bit uids. There's ways to get around that; I just wish we'd considered it when we started.
