  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns3.aok.de (217.111.83.17): read udp 46.225.38.91:57373->217.111.83.17:53: i/o timeout; ns4.aok.de (217.111.83.18): read udp 46.225.38.91:58731->217.111.83.18:53: i/o timeout.

    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026102137 on ns2.aok.de (217.110.254.18); 2026102152 on ns1.aok.de (217.110.254.17). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

Problems

  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx1.aok.de, mx2.aok.de
    #11
  • !
    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.
    #32
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
