In my experience spamassassin works wonderfully. There are some few false negatives (1-2 mails per week), but I did not have a single false positive which is very important for me. For example Google is much worse in that regard, which forces me to check spam every few days to ensure no legitimate mail ends up in spam, so it's like no spam filtering at all, I have to read it all anyway.
