We use the Surf Control product and have great success with it. It (along with a lot of other products) allows us to use Reverse DNS lookups and RBL lookups against incomming e-mail to block a lot of spam before it even gets through the door. After it makes it through those checks they have a nice Anti-Spam agent that is updated nightly. In addition, you can do dictionary checks to further eliminate spam and unwanted content. It also gives you the flexibility to setup "allow" rules to prevent known good domains from being submitted against the anti-spam filters. It took a few weeks to tune all the filters but since then it runs very well.
