You lie to it... If you put an entry in your DNS for smtp.freeserve.net CNAME mail.ourschool.sch.uk, then your DNS server will return that information. However, if your specific example is indicative of the others, then use the hosts file on the local computer to get a similar result. The webpages are best dealt with by Squid/Squidguard or similar. What does your primary proxy do now?

All of our clients now use this machine as primary DNS. The bind config is set to be authoritive for our own domain, and forward all other requests up stream to EMBC`s name servers. What I now want to do is "poison" the DNS cache with various entries for other (random) domain names. eg My laptop wants to send email to smtp.freeserve.net, which is right for home at school I need it to connect via our school email server. If DNS returned our internal IP for smtp.freeserve.net ..... problem solved! I also want to divert various web pages so that I can add additional web filtering to our system with out having to secondary proxy things. How do I do this?
