Exploiting Network Structure for Proactive Spam Mitigation
Overview E-mail has become indispensable in today's networked society. However, the huge and ever-growing volume of spam has become a serious threat to this important communication medium. It not only affects e-mail recipients, but also causes a significant overload to mail servers which handle the e-mail transmission. This paper performs an extensive analysis of IP addresses and IP aggregates given by network-aware clusters in order to investigate properties that can distinguish the bulk of the legitimate mail and spam. Their analysis indicates that the bulk of the legitimate mail comes from long-lived IP addresses. They also find that the bulk of the spam comes from network clusters that are relatively long-lived.
