Transport rules can do this for you, although it cannot reject the email at the point of delivery.

The rule will be something like

Sent to <address> from external sender, reject the message unless message from x

You could also try unless headers contain text, and put in the domain the messages come from.

The other way would be to create a contact for the external address, then use that to restrict the traffic.
