| Abstract(in English) | Recently, incidents of spam mail submissions via Message Submission Agent (MSA) in an organization, abusing illegally obtained passwords such as those used by password list attack, have been reported increasingly. In this paper, we propose a countermeasure against such incidents that detects spam mail submissions earlier using geographic information of each client derived from its source IP address. We also implemented a spam submission prevention system based on the proposed countermeasure. According to our operation experience of the system in Okayama University, we confirmed that the system works effectively. |
