Make a copy of you router that delivers messages to other hosts (it's
called "dnslookup" in the default exim.conf), put it just before that
router and modify it a bit, e.g. too look like this (remember to write a
"condition" that checks if a user should be allowed remailing the
Internet or not):

Put following just below your first router that delivers messages to
remote hosts (it's called "dnslookup" in the default exim.conf):

    restrict_dnslookup:
        driver = redirect
        domains = !+local_domains
        condition = ...
        allow_fail
        data = :fail: You are not permitted to send mail to the Internet


You have to write a valid "condition" yourself. "local_domains" is a
domainlist containing all your local domains.

Bye!
