Hi
a mailing list was created with MM2.1 by a another person and I am the list administrator. This list was created empty
so I started inviting people to join.
However, when I started to send trial messages to the list I received this error message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
   assemb...@llistes.ruderal.cat
   host llistes.ruderal.cat [159.69.3.30] SMTP error from remote mail server after RCPT TO:<assemb...@llistes.ruderal.cat>:     550 5.1.1  <assemb...@llistes.ruderal.cat>:Recipient address rejected: User unknown in virtual mailbox table
...
I don't understand why, especially because the unknown user's address is my address which is part of the users mailing list. Can anyone help understand why this happens and how to fix it? (right now I don't have access to the person who initially created the list)
Best regards


The user that's unknown is not you. It is the list assemb...@llistes.ruderal.cat.

If your MTA is Postfix as it appears to be and you are using Mailman's Postfix integration as described at https://www.list.org/mailman-install/node12.html and its subsections, this shouldn't happen.

If you are manually creating aliases and virtual mappings for your Mailman lists, you need to add the aliases and virtual mappings for this list.

If you need further help, please provide the output from

postconf -n

so we can see your Postfix configuration.
