DMARC Settings
The DMARC Settings page lets you configure DMARC policy, reporting, and alignment for your domain.
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 you to specify a different DMARC policy for subdomains. Set to No to have subdomains inherit the parent domain's DMARC policy.
Percentage
Specifies the percentage of emails to which recipient servers should apply the DMARC policy. All other emails have the next lower DMARC policy applied (e.g. if the published policy is Reject and the percentage is 30%, the remaining 70% have Quarantine applied).
Aggregate Reports
Report Interval
How often recipient servers should send aggregate reports.
This setting is usually ignored: most providers report on a 24-hour cycle regardless.
Reports Will be Sent to
Specify the email addresses that should receive the raw RUA DMARC aggregate reports.
Failure Reports
| Option | Description |
|---|---|
| Disabled | Failure report processing by DMARC Manager is disabled. |
| Enabled | Failure report processing is enabled. |
| Specific Recipients | Send failure reports to specific recipients other than the DMARC Manager platform. |
Report Options
| Option | Description |
