There are rules which say the domain must resolve for sender and receiver. There are rules which deny relaying. But are there rules which ensure the sender is an user of this machine by checking the username? I now get spam which claim to come from a non-existing user of my isp, i.e. 85231.@image.dk. Does a rule exist, which can stop _this_ kind of faking?
