I have couple of domains on Hotmail Live and one of the domain I want to restrict it's send/receive to within the domain. Is it possible? 

Example: *** Email address is removed for privacy *** should be able to send or receive mails from/to *** Email address is removed for privacy ***, and should not be able to send or receive mails from/to *** Email address is removed for privacy ***

Is this possible? If yes, please help to 'enable/setup' this feature.

Thanks and sorry if this is a dump idea/question
