The point I was trying to make is that our ISP actually does provide secondary MX service to some of its customers. This means that anybody needs to be allowed to relay through those machines to the domains they MX for. They don't need to be WIDE open, but they do need to allow relaying to all of the ISPs secondary MX customers. That, I think, is the excuse he uses for running an open relay. Bad excuse, yes. It apparently makes it easier for him to manage the mail exchangers. Only the DNS config needs to be updated, not the MTA config. I guess what I'm trying to accomplish is two-fold: 1) How best to filter email based on unsecured relays without pissing off the admins of secured relays with relay-checks. 2) How to drive the dolts who insist on running wide open relays off the net. -- -Paul Iadonisi Senior System Administrator Red Hat Certified Engineer / Local Linux Lobbyist Ever see a penguin fly? -- Try Linux.
