In an attempt to get even more aggressive about stopping spam, I turned on an option in postfix that requires the sending system to have a valid reverse DNS entry. When I did that, it started rejecting mail from this list sent by a system with the IP address 148.100.81.40. Can someone at Marist please fix this?
