Published record

v=DMARC1; p=none; pct=100; rua=mailto:a.zbsi3m5l@reports.hornetdmarc.com

What this means

• Politique p=none : surveillance seule, aucun message non authentifié n'est bloqué.
• SPF se termine par ~all (softfail) : acceptable en phase d’observation, viser -all à terme.
• Au moins une clé DKIM valide publiée.
