Allow relay internally only

I have a connector setup on my exchange server that we use for internal devices to relay..printers..scanners and so on. These devices connected to our relay server (20082r with smtp installed) which then makes the connection to exchange. Is there a way I can configure either of them to allow relay to only domains my exch org is responsible for?

I wrote a blog on the subject of internal email relay here: http://acbrownit.wordpress.com/2012/05/02/exchange-2010-relaying-how-to-use-it-how-to-turn-it-off/

Basically you would set up a receive connector that accepts unauthenticated email and set up the IPs it receives from to be only those on your internal network, or only specific IPs that represent devices or apps that need unauthenticated relaying. This, of course, assumes you are using Exchange 2007+.
Usually doamins are controlled by the send connectors, i.e, your smtp relay server.

There should be a possiblity of adding remote domains. Check this for reference

Thanks for the info guys. My relay is secured and configured properly.
What I am trying to do is have it setup so that relaying can be used internally only.
ie: if someone scans to email it will only send to domains my exchange org is responsible for.
I have been asked to secure this more as someone tried scanning a sensitive document and sending to a gmail account<can I prevent this?
