| Abstract(in English) | As the number of spam mail has been increasing and it occupies 85% of all email traffic, SMTP servers are frustrated with the task of filtering. To address this problem, it has been proposed that the SMTP server blocks spam mail before receiving the message body at the SMTP session by using host information or behaviors of spam sender clients. Although these proposals work well, they also lead false positives and false negatives. We propose an efficient spam mail-blocking system based on information obtained before receiving the message body at the SMTP session. In our proposal, we make the spam mail detection rile by using binary decision tree with the detailed feature element of spam mail. This method suppresses false positive rate minimally and detects spam efficiently. The preliminary result of our method using SMTP server's log was that it could block about 90-95% of spam mail with few false positives. We also discuss about some candidate features that may enable more accurate spam detection. |
