perl-Razor-Agent - Collaborative, content-based spam filtering network agent
- Description:
Vipul's Razor is a distributed, collaborative, spam detection and
filtering network. Razor establishes a distributed and constantly
updating catalogue of spam in propagation. This catalogue is used
by clients to filter out known spam. On receiving a spam, a Razor
Reporting Agent (run by an end-user or a troll box) calculates
and submits a 20-character unique identification of the spam (a
SHA Digest) to its closest Razor Catalogue Server. The Catalogue
Server echos this signature to other trusted servers after storing
it in its database. Prior to manual processing or transport-level
reception, Razor Filtering Agents (end-users and MTAs) check their
incoming mail against a Catalogue Server and filter out or deny
transport in case of a signature match. Catalogued spam, once
identified and reported by a Reporting Agent, can be blocked out
by the rest of the Filtering Agents on the network.
