I do. I have so few issues with SA rulesets (and sare rulesets) with FPs or missing spam [other than when new variations come in] that I'd rather put the load on my server. I don't agree with the methodology of sites like spamhaus & spamcop so I only use the scoring rules built into SA rather than just simply give blacklisting control to another service. - Skip
