[SOLVED] How do I do this - webmail and roundcube on the host, without a virtual server?

Good to hear that. I want PhpMyadmin and webmail as centralized so that users dont need to install from scripts for each account.
Can you guide me with step by step instructions as i am not very familiar with the virtualmin.

Note: A video tutorial will help many starters as this is a very common question among virtualmin users.
