The DMARC checker works by performing a series of technical steps:
- DNS lookups: It retrieves the DMARC record from the domain’s DNS record.
- Record parsing: It validates the record’s syntax and ensures all tags (e.g., ‘p’, ‘rua’, ‘ruf’) are correctly formatted.
- Authentication checks: The tool analyzes SPF record and DKIM record alignment to ensure the domain’s authentication protocols align with the DMARC policy.
- Reporting validation: The tool verifies reporting mechanisms, such as aggregate (‘rua’) and forensic (‘ruf’) reports, ensuring that email feedback is appropriately configured.
For example, if your DMARC policy is set to ‘p=reject’, the tool will check that SPF and DKIM are correctly aligned to enforce the policy for non-compliant emails.
