メールの蔓延は電子メールにおいて深刻な問題となっている．特に，宛先不明により送り返されるバウンスメールの，詐称発信者に対応する特定のMTA（Mail Transfer Agent）への集中は，ネットワーク資源や計算機資源を大量に消費し，またMTA の過負荷により通常の電子メール（通常メール）の配送に遅延が生じる点で非常に深刻な問題である．そこで，本稿では中小規模の組織を対象としたバウンスメール集中への対策方法を提案する．本方法では，中小規模の組織ではバウンスメールの大部分が普段は電子メールをやりとりしていないMTA から送られる点に着目し，主にバウンスメールを処理するMTA を追加して通常メールとは分離して処理を行う．これにより，通常メールを処理するMTA は負荷が軽減され，通常メールの配送遅延を抑えることが可能になる．実際の事例におけるアクセス記録を分析した結果，本方法はバウンスメールと通常メールを十分高い精度で分離し，通常メールを処理するMTA

serious problem on e-mail environment. Particularly, spam mails with a spoofed sender address is very serious, since they make the MTA (Mail Transfer Agent) corresponding to the spoofed address be overloaded with massive bounce mails generated by the non-deliverable spam mails, and since they waste a lot of network and computer resources. In this paper, we propose a protection method of the MTA against such massive bounce mails, which is suitable for relatively small sites. This method introduces additional mail servers that mainly deal with the bounce mails, considering that the most MTAs sending back bounce mails are likely to have never sent any mails to the target domain recently. This causes the load of the original mail server to be reduced. According to the analysis of the access logs in the the practical example we have experienced, we confirm that the proposed method can fairly separate massive bounce mails from normal mails and can effectively protect the original MTA against massive bounce mails.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1020","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1010","bibliographicIssueDates":{"bibliographicIssueDate":"2006-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"47"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"電子メール"}]},"weko_creator_id":"1"}}
