However, I'll add my voice that I believe "reputation" systems as an approach to spam-prevention are neither useful nor sufficient w/o repeating what others have said.
Agreed. If my grandmother has a "reputation" for sending legitimate email, and she inadvertently installs some spam zombie software, it is certainly feasible (and probably trivial) for the spammer to steal all her credentials and thus her "reputation". Spam will get out for a while, but once her "reputation" significantly degrades, it will be stopped -- as will any future legitimate email from her. This "solution" strikes me as worse than the problem it tries to address. S Stephen Sprunk "Those people who think they know everything CCIE #3723 are a great annoyance to those of us who do."
