Oh, I didn't expect that version 2 was still alive. I'm sorry about my mistake. Thank you very much for help and the hint to the commands. With the help of the commands, I was able to determine that quite a few users were actually disabled, although this was not clear from the settings. Probably the users were disabled after several emails could not be delivered to them. After I explicitly enabled them in the interface, they are no longer disabled according to the commands. I hope now that all problems are solved with that. -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1756009 Title: emails are not delivered to all recipients To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1756009/+subscriptions
