Abstract(in English) Recently mass-mail sending is becoming a serious problem that prevents normal commerce and advertisement on the Internet. We are now developing a system solving this problem. Existing mass-mail filtering systems can be classified into two types; 1) open relay MTA based filtering systems and 2) recognition based contents filtering systems. Since the number of open relay MTA is much bigger than the number of mass-mail contents, contents based mass-mail filtering is much effective than the open relay based filtering. However, the recognition based contents filtering requires time consuming training and tuning. Unlike these approaches, our system consists of two parts; mass-mail checksum database and clients. The checksums are delivered via the DNS and the clients. The prototype database system is currently running, i.e., mass-mail contents sent to some dummy addresses are analyzed, normalized, and their checksums are stored into the DNS. As well, some clients referring the DNS are developed. This report presents the overview of our current system and the future extensions.
