DMARC Existence
Phishing Attack Prevention
Why this matters
DMARC provides a stronger email domain authentication than having just SPF. Also, without DMARC, you would not be able to have an aggregated report for SPF and DKIM.
Steps to fix
- Confirm SPF is already enabled for your domain — DMARC depends on SPF (and/or DKIM) being set up first.
- Check with your System Administrator or mail provider to publish a DMARC TXT record for your domain.
- Start with a monitoring-only policy (p=none) so you can review DMARC aggregate reports before enforcing stricter handling.
- Re-run the scan (Rescan domain) to confirm DMARC is now detected for your domain.
