Is there a way to block all messages that are "from" my domain but are not valid accounts or aliases setup in my domain? We've been getting a lot of infected zip files lately that are claiming to come from email addresses that don't exist in our domain. I realize that I can just explicitly block those that I've identified, but I want to know if there's a way to block future ones as well without explicitly knowing what they are.
