Understanding Proactive vs. Reactive Methods for Fighting Spam

To date, spam filtering techniques have fallen into several categories: blacklists, rules and heuristics, or more recently, Bayesian filters and signature technologies. However, none of these existing reactive approaches, have done an adequate job of solving the spam problem. These existing techniques result in a constant battle of misclassification – either in the form of a legitimate message being mistaken for spam (false positive) or a spam message being mistaken as legitimate (false negative).

This paper introduces a proactive approach to dealing with spam. IBF technology reads email like a human. It determines the message's intent and moves legitimate email straight to the mail server. It is the only system that achieves both high filtration rates and low false positive rates simultaneously with no ongoing maintenance.
