You can use Information Rights Management (IRM) which allows individuals to specify access permissions to e-mail messages. By using IRM, it helps prevent sensitive information from being printed, forwarded, or copied by unauthorized people. After permission for a message has been restricted by using IRM, the access and usage restrictions are enforced no matter where the information is, because the permissions to access an e-mail message are stored in the message file itself.
Details on how to register for IRM service (Free service) can be found at Introduction to using IRM fro e-mail Messages
