Restricting sending mail to domain or group

Can the groups send and receive from outside the domain ?  If so, it's
going to be difficult to prevent groups from seeing each others emails
because an email that originated from group A could be sent to some
other domain (out on the internet), then get forwarded to a user in
group B.  Just a thought.
