| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As the number of spam mail has been increasing and it occupies 80% 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 block spam mail at a high rate, they also block legitimate mail, which causes a great deal of trouble to legitimate SMTP clients because they are forced to resend email. We propose an efficient spam mail-blocking system based on information obtained before receiving the DATA command at the SMTP session. This method suppresses false positive rate minimally and works as a lightweight primary filter. The preliminary result of our method was that it could block 94.5% of spam mail and it's false positive rate was limited to 0.1%. | |
