The majority of earlier studies on the email spam have focused on the contents of email messages so as to distinguish spam messages from legitimate ones. However, there is a growing realization in the networking community that effective anti-spam techniques can be developed only with a clear understanding of the spammer behavior at various levels, in particular, the network-level behavior. Behavioral characteristics of spammers such as the statistics of spam messages from different spammers, the spam arrival patterns across the IP address space, the number of mail servers in different (Spam) networks, and the active duration of spammers, can significantly affect the effectiveness (Or even the feasibility) of many anti-spam mechanisms.
