SpamAssassin with all the signature matching (razor, pyzor, etc)
and well-trained baesian filter should do just fine.

Only real work you'll need to do is to set up a way for users to identify
misjudged spam. I usually set up a per-user spam mailbox, where all the
spam which got through is placed. From there it's picked up by a daily
(for my volume of mail) cron job, processed by sa-learn, and then removed.

You'll have to educate your users about spam/ham mailboxes, of course.
