Default virtual server when pointing to server

Hello,

I wonder how I can change the default virtual server which the domains I point to my server is getting.

I wonder how I can change which of my virtual servers the domains (when not adding any own virtual server to the domain) I point to my server should end up with. I have figure out that the domains I point to my server automatically shows up to the first server in the list.

Example: I have bought a new domain from eg GoDaddy, the domain is big-cars.com. After I bought my domain I point the DNS to my Virtualmin server. Thus, I point big-cars.com to the Virtualmin server.

Before I have created any site that take care of the domain big-cars.com in my Virtualmin CP, this domain will point automatically to the site I have first (in alphabetic order) on my Virutalserver eg abc.com

I wonder how I can change this so all the new domains I have bought I pointed to my Virtualmin server automatically should link to another site eg giraf.com?

How can I fix this?
