I have an Exchange 5.5 Server that is live on the web.

Some one is sending messages throught it. I need to stop them from doing this.

Do I go into the Internet Mail Connector and go into the Routin gRestrictions Option then only allow the internal IP address and live ip address of the server in the allow routing messages?

To close the relay do the following:

Internet Mail Service and Routing

Then select reroute incomming SMTP mail

Then add your mail domain name to the box as "should be accepted as inbound"

Routing restrictions can be left blank, with the only tick on "Hosts and Clients with these IP Addresses".

You do not need to fill in anything else, this will stop message relaying and only accept inbound mail to users on the global address list.
