Abstract
A method for automated evaluation of a SPAM filter rates a sender-receiver pair based on traffic information related to the sender-receiver pair. A SPAM filter intercepts electronic messages transmitted between the sender-receiver pair and classifies them as either SPAM or HAM. On comparing the rating for the sender-receiver pair and the classification for an electronic message between the sender-receiver pair, the method generates a metric indicating the reliability of the spam filter. Repeating these steps for more than one electronic messages and related sender-receiver pairs, the method produces a set of metrics. One or more of the metrics from the set of metrics are used to calculate an evaluation factor for evaluating the SPAM filter.
