Filtering for Exchange

I have exchange via Windows SBS 2003 R2 setup on my private network.  We do not host our own email, and use our ISP via pop3 accounts for all externally bound email.  A few individuals will still need access to their POP accounts but most will only need internal email.

I configured the exchange server as an email gateway to forward all mail to the ISP and use the POP downloader to then send mail back to the correct users.  
Currently I am finding out that an internal only users can send email to the internet, although they won't be able to recieve anything back because they don't have a POP account.

What I am asking is if there are rules or filters where I can stop this from happening?  I still want the functionality for some to use exchange to send & rec. the POP3 mail, but for others it should not be forwarded to the ISP.
