Hi! We're running postfix-us...@postfix.org and we're encountering an odd problem: A system is sending mailing list messages that were posted on postfix-us...@postfix.org BACK to postfix-us...@postfix.org
And these mails simply pass moderation (which is set to the following): Default action to take when a member posts to the list: Default processing Default action to take when a non-member posts to the list: discard (no notification) The headers of the mail (which I put on hold, based on the IP of the sending system): Date: Thu, 24 Oct 2024 11:13:01 +0200 To: postfix-us...@postfix.org Message-ID: <zxopnerojaid0...@castor.ghen.be> In-Reply-To: <zxomla6s1lugy...@chardros.imrryr.org> X-MailFrom: ge...@hendrickx.be X-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation; header-match-postfix-users.postfix.org-0; nonmember-moderation; administrivia; implicit-dest; max-recipients; max-size; news-moderation; no-subject; digests; suspicious-header X-Mailman-Version: 3.3.9 Precedence: list Content-Type: text/plain; charset="us-ascii" Message-ID-Hash: Z6I2WZCEBC6PUKLVOEVAW3ZU2CDR47AW X-Message-ID-Hash: Z6I2WZCEBC6PUKLVOEVAW3ZU2CDR47AW X-MailFrom: t...@turbopush.cn X-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation; header-match-postfix-users.postfix.org-0; nonmember-moderation; administrivia; implicit-dest; max-recipients; max-size; news-moderation; no-subject; digests; suspicious-header Subject: =?utf-8?B?W+WklumDqOmCruS7tl1bcGZ4XSBb5aSW6YOo6YKu5Lu2XVvlpJbpg6jpgq7ku7ZdUmU6IE9wZW5TU0wgY29tcGlsZSB2cy4gcnVudGltZSB2ZXJzaW9uIHdhcm5pbmc=?= From: Geert Hendrickx via Postfix-users via Postfix-users <postfix-us...@postfix.org> Reply-To: Geert Hendrickx <ge...@hendrickx.be>, Geert Hendrickx via Postfix-users <postfix-us...@postfix.org> So, it's the mail from "Geert Hendrickx" being resent from t...@turbopush.cn -- the headers have both "X-MailFrom: t...@turbopush.cn" (not a member of the list) and "X-MailFrom: ge...@hendrickx.be" (definitely a member of the list) Why is the mail being accepted? From: doesn't look right (since it says "postfix-us...@postfix.org") We're currently stopping these mails, but I think mm3 is not acting correctly here (unless we're missing something) -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebra...@charite.de https://www.charite.de ------------------------------------------------------ Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/ Member address: arch...@jab.org
