I agree with Mark -- I don't see how to do this without changes to the code. Also, note that even if you could configure this as you desire, the CC addresses will be delivered. But people who subscribe but aren't CC'd will receive the post only if and when the post is released from hold. Only you can decide whether that's desirable, but it's likely some subscribers will be unhappy about it.
This is an important point.
If your goal is to prevent exposing those non-member addresses in Cc:, etc. in posts from the list, then all this may help, but if your goal is to prevent list posts from going to non-members, you can't accomplish that. by the time mailman receives and perhaps holds the post, it will already have been sent to all the directly addressed To:, Cc: and Bcc: recipients.
