Hi together,
I discovered last friday that my mailing list are not working at the moment. When I send a mail to one of my lists I get the error message "Recipient address rejected: User unknown in virtual mailbox table;"
So I checked the configuration of Postfix and discovered that the files transport and mailboxes in /etc/postfix/imscp doesn't have any Mailman specific entrys. So Postfix doesn't know to handle mails for mailman.
I tried to disable and enable to plugin. but with no success. I also upgraded from I-MSCP 1.1.16 to 1.1.18 today with no success also.
So someone has an idea whats the problem is and how I can resolve it?
