You can try it yourself, with telnet and proper smtp commands. For
example, telnet from outside of your organization to your mail server
mail from: foobar at example.com
rcpt to: foobar at example.org
You actually have to get error message about relay denied for you. If
you don't - you're in trouble.
If you do recieve such message - you relay is closed and probably you
have spam worms who send emails from legit user, or something like that.
