I can add firstname@mydomain.net but if I try this for yourdomain.net I got an error like: Name already exist. Did anybody have an idea how I can solve this problem.
Unix username and Virtualhost owner for mydomain.net is firstname
for yourdomain.net the unix username is yourdomain
I changed the unix user and groupname from mydomain.net to “mydomain” instead of firstname.
This works fine, but in the Virtualmin “Edit Server” the unixgroup of the Domain is still “firstname”. But the group “firstname” is no longer available on this system.
Where does Virtualmin save the Unixgroup of a Virtual Server?
