Abstract

Spam is the unsolicited electronic mail for a commercial advertisement or unwholesome information. Spam filtering can be applied at the client level or the server level. In this paper, we focus on filtering spam at the server level. In order to block the spam at server level, various filters for mail servers have been developed. However, previous techniques did not consider the traffic pattern or volume of mail and continuousness between a mail and a worm. In addition, they applied uniform filtering rules. All these facts make mail servers downgraded. In this paper, we apply dynamic spam filtering rules for blocking spam and worm.
