On July 25, 2024, between approximately 5:30 PM ET and 7:00 PM ET, DMARC results with a reject policy were sent to quarantine rather than bounced as per RFC. This temporary change was made after reports of false DMARC failures. The team evaluated the logs and spotted intermittent SPF failures in the DMARC evaluation process. An adjustment was applied to eliminate the SPF check failure. As of 7:00 PM ET, a failed DMARC with a reject policy has resumed bouncing those emails. Evidence of emails bounced due to a sending domain's DMARC policy will be found in the logs. NOTE: A DMARC policy is set by the owners of the sending domain, not Mailprotector or a recipient. If the policy is set to reject messages that fail DMARC alignment, the bounce is made regardless of Allow rules.
