  1. Beat Spam Using Hashcash

    Shell writes "If they want to send spam, make them pay a price. Built on the widely available SHA-1 algorithm, hashcash is a clever system that requires a parameterizable amount of work on the part of a requester while staying "cheap" for an evaluator to check. In other words, the sender has to do real work to put something into your inbox. You can certainly use hashcash in preventing spam, but it has other applications as well, including keeping spam off of Wikis and speeding the work of distributed parallel applications." If you're specifically interested in hashcash for your mail server, Camram has some interesting ideas -- their Frequently Raised Objections page may be illuminating.

    esj at harvee writes "Recently the Camram project released its latest version of a hybrid sender-pays anti-spam system. The project has proven that sender-pays works and has demonstrated how to make it work with existing e-mail systems. Camram has developed hybrid sender-pays techniques that scale down to the desktop and up to the enterprise. It's a completely decentralized system that can put spam-fighting power in the hands of individuals. It gives you control of not only the current generation of spam, but also any future commercial spam -- why replace Viagra ads from a scam artist with Viagra ads from Pfizer?"
