I recently followed the instructions here https://github.com/g4rf/dockerized-mailcow-mailman, and was able to create a new Mailman 3, Debian-based installation. I then followed the instructions here https://docs.mailman3.org/en/latest/migration.html in order to migrate from my old, Centos-based installation, to the new, Debian-based installation. It seemed to work well, but unfortunately a problem showed up.
Whenever someone posted to one of the lists on the new installation, the messages were rejected by Postfix: postfix-mailcow-1 | Aug 5 20:55:48 ef2b760c2e61 postfix/cleanup[8681]: B7B856099EC: message-id=<a8946b8e-2a47-4701-9548-4544981fa...@gmail.com> postfix-mailcow-1 | Aug 5 20:55:49 ef2b760c2e61 postfix/cleanup[8681]: B7B856099EC: milter-reject: END-OF-MESSAGE from unknown[172.22.1.1]: 5.7.1 This message does not meet our delivery requirements; from=<mylist-boun...@myserver.dk> to=<mylistus...@gmail.com> proto=ESMTP helo=<[172.19.199.4]> postfix-mailcow-1 | Aug 5 20:55:50 ef2b760c2e61 postfix/cleanup[8681]: 216D36099EC: message-id=<a8946b8e-2a47-4701-9548-4544981fa...@gmail.com> postfix-mailcow-1 | Aug 5 20:55:50 ef2b760c2e61 postfix/cleanup[8681]: 216D36099EC: milter-reject: END-OF-MESSAGE from unknown[172.22.1.1]: 5.7.1 This message does not meet our delivery requirements; from=<mylist-boun...@myserver.dk> to=<mylistus...@mail.dk> proto=ESMTP helo=<[172.19.199.4]> So, for each of the existing lists, I had to delete the old list and create a new one - with the same name and the same users. After this, everything seems to work as expected. Thanks for all the work you all has put into this, Jesper _______________________________________________ Mailman-users mailing list -- mailman-users@mailman3.org To unsubscribe send an email to mailman-users-le...@mailman3.org https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ Archived at: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/6NO2XWJA3PWZDO52Z7JEVZETNGUMXGRI/ This message sent to arch...@mail-archive.com
