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.

What this means

• Aucun enregistrement DMARC publié (_dmarc.<domaine>). Les destinataires n'ont aucune politique à appliquer.
• SPF se termine par ?all (neutre) : n’apporte aucune protection effective.
• Au moins une clé DKIM valide publiée.
