Well, the encryption folder only secures the data inside the email, I don't think it would prevent a user from forwarding it. GroupWise has the same encryption features, but again, it only secures the data.You can try looking into a product called GWAVA. It will monitor the MTA of your domain and will prevent both internal and Internet forwards of confidential email. But there is currently nothing with in GroupWise that can acomplishwhat your asking for.
