Unsolicited Bulk E-mail (UBE) or spam constitutes a significant fraction of all e-mail connection attempts and routinely frustrates users, consumes resources, and serves as an infection vector for malicious software. In an effort to scalably and effectively reduce the impact of these e-mails, e-mail system designers have increasingly turned to blacklisting. Blacklisting (blackholing, block listing) is a form of course-grained, reputation-based, dynamic policy enforcement in which real-time feeds of spam sending hosts are sent to networks so that the e-mail from these hosts may be rejected. Unfortunately, current spam blacklist services are highly inaccurate and exhibit both false positives and significant false negatives.
