I've been using SpamAssassin since December, and have been very pleased with the results; so have 99% of my customers. The few recurring false-positives are easy enough to whitelist, and very few false negatives slip through... For the price (free) and the server load (minimal), you can't beat it. The latest version(s) is(are) much better than previous ones.
