I recently rebuilt my server (Ubuntu 20.04) and rebuilt mailman 2 - upgrading to the latest version 2.1.34. The mail server is postfix I run three mailing lists, including "TESTmail". The same issue below affects all three lists. On the General Page, I have filled in an administrator and a owner. The list options are set up that emails from non-members are held and the moderator should be notified. * The poster of the email receives a notification that the email is being held * The moderator does not receive any messages * But looking at the postfix logs, it appears to me that mailman does try to send a message to the moderator Apr 5 22:12:05 ip-xxx-xxx-xxx-xxx postfix/smtp[9473]: 6D0973EB91: to=<testmail-owner@lists.xxx.org.uk>, But, the email message is being sent to the generic owner, rather than the specific names filled into either the moderator or administrator boxes on the general tab. Also, I note that the footer of the mailing list has: TESTmail list run by testmail-owner at lists.XXX.org.uk rather than the specific owner. Any clues as to what is not quite correct in the mailman setup?
