On 9/24/02 I mentioned MailFrontier's pending patent on an anti-spam system that responds to unknown senders with an emailed challenge. I mentioned that a patent on that might be problematic because many people have no doubt been thinking about it for years.
Today, in response to that post, I received word of this prior art.
