Spam behavior recognition technology,especially the behavior recognition technology based on the e-mail flow was studied.According to the communication topology of legitimate e-mail and spam with large differences,this paper introduced the concept of similarity,proposed a behavior recognition technology based on the similarity of topology.With this method,the e-mail receivers and senders were marked by the contact list.The e-mail users were divided into e-mail user clusters by calculating similarity.The senders and receivers of the coming e-mail were classified to clusters to judge whether the e-mail was spam.This paper used an auxiliary filter for classification and recognition of the original e-mail information.Simulation test with real e-mail set was conducted,which shows that the method based on the similarity of topology provides a better result for spam classification.
