| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With the wide use of e-mail, it has become commonly expected that e-mails are delivered to recipients immediately. It is not rare that a huge amount of e-mails are delivered to a mail transfer system in a very short time unintentionally. Such e-mails sometimes causes excessive load to the system and to increase traffic of network, and e-mails are delivered with serious delay in such situations. We propose a mail transfer system to detect efficiently such e-mail with each pair of envelope-from and envelope-to address managed by a hash table. In proposed system, the number of each pair envelope-from and envelope-to address is counted, and if the number of the delivery including a specific pair (envelope-from, envelope-to address) during a short period exceeds a pre-specified threshold, we regard this pair as a cause of a huge amount of e-mails. We prepare multiple hash tables which managed envelope-from and envelope-to address to prevent an increase in scale of the hash table, and we divide such hash tables every time and empty all entries at fixed intervals. We also prepare for the blocklist to judge a huge amount of e-mails beforehand. We implement the proposed system and evaluate it. | |
