there are four columns in the Allow/Block page [Action, Address/domain/ip address, Created on and Sender authentication ]. It would be useful to know if an allowed address fails the sender authentication check. When a client asks us to allow an address we do not have time to test to see if the address the client requested us to allow passes the sender authentication check before adding to the allow list. If you could add column or two to the screen. Number of messages that failed sender authentication in the last 30 days. Number of messages that passed sender authentication in the last 30 days. The idea is if there are messages failing we can contact the sender t oget them to increase their security and once they are passing the authentication check we can enable it.
