Problems

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns.medien-systempartner.de (80.228.114.1): dial tcp 80.228.114.1:53: i/o timeout.
    #19
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.medien-systempartner.de: "9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.4". Hide or replace the version string.
    #17
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx3.medien-systempartner.de, mx4.medien-systempartner.de
    #11
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:report-dmarc@medien-systempartner.de (needs nwzonline.de._report._dmarc.medien-systempartner.de). Ask the report provider to publish the record, or check the address.
    #29
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
