Startup Uses Receiver Reputation to Combat Spam

I can see receiver reputation emerging as a new front in spam mitigation, but I wonder about whether false positives would limit its adoption in large companies and in certain industries.

While there’s nothing in the article that says so, you’d have to think the executives who run this company have filed the relevant patents. It will be interesting to see how major anti-spam players — Symantec, Cisco, McAfee, and Secure Computing — respond if this approach proves effective.
