Not sure what you are using as your solution.....but we just installed a Barracuda here and it dropped our spam rate to about 1 in 18,000 (from 1 in 25-30). The thing is a lifesaver. It took a little while to setup (maybe 1/2 day) and "learn it" with samples of good and bad mail, but it was very worthwhile.

We can't filter forever because that doesn't work. Reactive IP blocking is a step in the right direction but still not a solution. It seems a list of people that can email is easier to keep than a deny list. We're blocking over 40,000 IP's after a few weeks. The tool we've written is quite enlightening but surely there's someone thinking of a solution as spam grows to 95%+. What happens when it's 99.999%???

By definition, our counter-attacks will always be a step behind, preferably a quick, short step. I don't think spending $100s or $1000s to attend a spam conference, if such a thing exists, in search of magic bullets is money well spent.
