Has anyone experienced unauthenticated emails being delivered to Google recipients despite having a DMARC policy (quarantine or reject) in place? We have seen evidence that unauthenticated emails (not passing both SPF and DKIM) are being delivered to Google, despite a DMARC policy, when messages pass through a 'forwarder', as noted by Google. We are trying to better understand this behavior and whether or not anyone has found a solution? Any insight or recommendations would be appreciated.
