where a dedicated receiving MTA receives all messages sent from trusted sending MTAs and performs only simple anti-spam measures, have been proposed so far to reduce delivery delay due to heavy spam

However, existing systems have some problems such that the dedicated receiving MTA easily receives even spam mails sent from trusted sending MTAs only through simple anti-spam measures. In this paper, we propose a method to perform full anti-spam measures on suspicious messages sent from trusted sending MTAs, by introducing tempfailing and SMTP session abort on the dedicated receiving MTA.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"102","bibliographic_titles":[{"bibliographic_title":"インターネットと運用技術シンポジウム2013論文集"}],"bibliographicPageStart":"99","bibliographicIssueDates":{"bibliographicIssueDate":"2013-12-05","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2013"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:43:19.154956+00:00","id":96468,"links":{}}
