  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.routing.net (134.0.30.178): REFUSED, authoritative=false; ns1.routing.net (2a03:2900:3:1::2): REFUSED, authoritative=false; ns2.routing.net (194.50.113.2): REFUSED, authoritative=false; ns2.routing.net (2001:4d8f:2::2): REFUSED, authoritative=false; ns3.routing.net (194.126.196.2): REFUSED, authoritative=false; ns3.routing.net (2a03:2902:3:1::2): REFUSED, authoritative=false.

  • ✗
    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: ns1.routing.net (134.0.30.178): ; ns1.routing.net (2a03:2900:3:1::2): ; ns2.routing.net (194.50.113.2): ; ns2.routing.net (2001:4d8f:2::2): ; ns3.routing.net (194.126.196.2): ; ns3.routing.net (2a03:2902:3:1::2): .

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: nsh.ipn.de: "9.16.1-Ubuntu". 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
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    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: mail.minuskel.de
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    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.
