Have turned on self authentication and all seems to be working correctly except that DMARC reports indicate that all messages to Verizon Media (Yahoo) are failing DKIM. There is a 'permerror' on all DMARC records. Any ideas? All other email hosts pass DKIM.
Thank you for reaching out to the Community! I recommend calling our Delivery Team for more information about this, and it should be an easy fix. Thank you!
