DMARC-Richtlinie

Domain-basierte Nachrichten-Authentifizierung und Berichterstattung

Policy: none

⚠️ Ihre DMARC-Richtlinie ist auf "none" gesetzt. Mailserver überwachen nur – sie lehnen keine gefälschten E-Mails ab.
This means mail servers will only monitor reports — not reject spoofed emails.
Consider upgrading your policy to p=quarantine or p=reject once SPF and DKIM are properly configured.
