If you install Exchange 2010 properly, your users can send emails internally as well as externally.

If you dont want users to send emails to / - you can setup a Transport rule and notify the sender, that this is a violation of company policy.

See here

OR you can block access to hotmail via firewall
I am really not clear what your question is ? Can you explain what you are trying to do

You can setup transport rules according to that article.

It's better to set it up for hotmail / yahoo / gmail (big3).
When  users start getting automatic alerts - they know they are being watched and you can put a note - that your last action was logged in the system for compliance purposes :).

People stop emailing after that.
