DMARC Configuration Settings & Setup
The DMARC settings page shows all the options available for DMARC configuration.
Policy Settings
| Policy | Description |
|---|---|
| None | Monitors email without taking action; reports are sent but no messages are blocked or filtered. |
| Quarantine | Suspicious emails are marked and delivered to spam or junk folders. |
| Reject | Emails that fail DMARC are completely blocked and not delivered. |
Apply Different Subdomain Policy
Allows users to specify a DMARC policy for subdomains. If this is set to 'No', subdomains will inherit the parent domains' DMARC policy.
Policy Percentage
This allows users to specify the percentage of emails to which recipient servers should apply the DMARC policy. All other mails will have the next lower DMARC policy applied (i.e. if the published policy is Reject, and the Policy Percentage is 30%, 70% of mails will have a Quarantine policy applied to them).
Policy Percentage is being deprecated and is generally not a recommended.
Aggregate Reports
Report Interval
The frequency with which the user would like to receive reports
This setting is usually ignored, with reporters often reporting on a 24 hour cycle).
