Enabling DMARC checking for incoming email
DMARC performs email authentication with, and is contingent on, SPF and DKIM checking. If either SPF or DKIM check passes, DMARC check will pass. If both of them fail, DMARC check will fail.
- Go to Profile > AntiSpam > AntiSpam and click New, or edit an existing profile.
- Under Scan Configurations, enable DMARC and assign the Discard_Inbound action from the drop-down menu.
- Click Create or OK.
