Exchange Transport Rule

Please help, I’m using exchange 2007, I created a transport rule to block user send email outside our organization, it works fine until today, I found out if user put an internal email address and external email both in to, then they can send email outside. Please see attachment for my rule, and how can I block this? Thank you.

i'm wondering is this by design.. if so you can try with message header..
no this is not by design at all and this should not happen.

the email will be received inside but the external email will bounce back.

are you sure the external email is being received?
