Method of countering unsolicited IP applications using lists

Method of countering IP applications spam using lists, namely blacklist and whitelist, is introduced in this paper. This function of an application server provides two-phase anti-spam technique using two kinds of lists. The first is using blacklist and whitelist of the IP application recipient, and the second is using the unified lists of other users. When an IP application is not identified whether it is a spam or not with the lists of the recipient, the anti-spam system uses unified list of other users. For the spam identification and treatment of an IP application, this method also uses other functions such as spam score management function, spam reporting function, and etc.
