which temporarily refuses the first delivery attempt of a message from an untrusted Mail Transfer Agent (MTA), is one of typical anti-spam technologies commonly used in many organizations. This method can refuse spam mails considerably. However, it also may refuse legitimate mails sent from domains resending the temporarily failed message with a different MTA or those without resending function. In such a case, an administrator of the receiver MTA has to register those domains by hand. In this paper, in order to reduce these drawbacks, we propose an anti-spam method introducing SMTP session abort function. This method performs the same effect as existing tempfailing methods by means of SMTP session abort during the first delivery attempt. In addition, this method can obtain the header or the whole message even if it would not be resent and can use the header for second delivery checking and can use the whole message of unresent messages in case of false positives. According to the operation tests of the prototype systems, we confirmed that the proposed method received messages from domains using a different MTA for retry.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"949","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"940","bibliographicIssueDates":{"bibliographicIssueDate":"2009-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"50"}]},"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":"分散システム運用・管理技術"}]},"weko_creator_id":"1"},"updated":"2025-01-22T03:09:56.500245+00:00","created":"2025-01-18T22:44:30.499846+00:00","links":{},"id":9235}
