Are you saying that if I have a few domains that I want to host websites and email on I should buy a separate technical domain to configure Ubuntu and ISPConfig with then just configure ISPConfig with my real domains?
Does that mean I wouldn't be able to accept email or run a website on my technical domain?
Is there no way around this, I know domains are cheap but it's another thing to spend money on.
