Executive Summary

This paper proposes SocialFilter, a trust-aware collaborative spam mitigation system. SocialFilter enables nodes with no email classification functionality to query the network on whether a host is a spammer. It employs trust inference to weigh the reports concerning spamming hosts that collaborating spam-detecting nodes (Reporters) submit to the system. Subsequently, SocialFilter weighs the spam reports according to the trustworthiness of their reporters to derive a measure of the system's belief that a host is a spammer.
