AN AUTHENTICATED CORRESPONDENT DATABASE

摘要

A system that can intelligently drive down false positive rates with regard to identification and/or classification of spam correspondence is disclosed. Authentication information from sending domains can be stored and used to establish confidence and drive down the false positives related to acceptance and/or classification of communications. A correspondent database of known correspondents can be constructed using the authenticated information. Accordingly, decisions (e.g., white and black list) can be better informed by employing relationship and correspondent communication pattern data which is maintained within the correspondent database.
