Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.mhn.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
