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.
We do provide a report for Message Authentication failures. Up to 365 day view of this can be filtered and on the main dashboard as well. See last screen shot for the column for Auth failure with hyperlink that takes you to the Message History for each of the messages. Note it is also export enabled. I applaud your effort to contact senders to fix their message authentication and hope you have lots of success getting that done. Many people simply don't understand DMARC, SPF, DKIM.
The report is clickable and takes you to message history which provides all the detailed information you would need to discover sender/receiver which is all that is required to add to an allow/block list. We even give you the option from the message details window to add the user or domain to a blocklist by clicking a button. In addition there is a category filter in Message History search that will show you which messages failed authentication.
In regards to printing end user allowlist/blocklist that is a feature that is coming in late June of 2023. Admins will have access to edit individual user allowlist and blocklists as well as export/import.
