Let's say you have your Linux box hosted on the net, and you start getting spam at root@yourmachine.net. How do you configure exim4 so that email to root is ONLY accepted from the local machine? In other words, script failures and cron messages can get emailed to root, but someone outside your machine can't email to root@yourmachine.net.

Is that possible?
