- • Politique p=reject : protection maximale contre l’usurpation.
- • SPF se termine par ~all (softfail) : acceptable en phase d’observation, viser -all à terme.
- • Au moins une clé DKIM valide publiée.
How to fix it
Marc, the DMARC copilot, finds every sender, writes the exact DNS, and walks your domain safely from p=none to p=reject.
