Global recipient blacklist in Exchange

We are using Exchange 2010 to send some types of communication to our customers (most of the customer traffic goes out via postfix, for which I already have a blacklist - see http://rdsrc.us/GT92bX).

We would like to implement a company-wide recipient blacklist, not just at the application level, but also at the Exchange 2010 level, as a final catch for legacy applications that might be sending mails that we don't know about.

Is there some way of giving Exchange 2010 a global list of external recipients, to whom no emails should ever be sent?

Many thanks

This is not possible. Ine option would be to create a transport rule and add all the email addresses but that would be a nightmare to manage
