Vipul's Razor is a collaborative, distributed, spam detection and filtering network. Through user contribution, Razor establishes a distributed and constantly updating catalogue of spam in propagation that is consulted by email clients to filter out known spam.
Detection is done with statistical and randomized signatures that efficiently spot mutating spam content. User input is validated through reputation assignments based on consensus on report and revoke assertions which in turn is used for computing confidence values associated with individual signatures.
What's New in This Release:
· The discovery logic used for discovering Razor2 servers was updated.
· Several long-standing issues were fixed in discovery and TCP connectivity logic.
