    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.swu.de (glue 62.116.159.81, 2001:4178:3:a357:62:116:159:81, zone 217.160.80.161, 2001:8d8:fe:53:217:160:80:161); ns2.swu.de (glue 217.160.113.113, 2001:8d8:580:401:217:160:113:113, zone 217.160.81.161, 2001:8d8:fe:53:217:160:81:161); ns3.swu.de (glue 89.146.248.78, 2a01:130:2000:118:89:146:248:78, zone 185.132.35.161, 2607:f1c0:fe:53:185:132:35:161); ns4.swu.de (glue 74.208.254.77, 2607:f1c0:1800:8091:74:208:254:77, zone 185.132.34.161, 2607:f1c0:fe:53:185:132:34:161). Update the glue at your registrar.

    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: mx6.kvnbw.de, mx7.kvnbw.de, mx8.kvnbw.de, mx9.kvnbw.de
    #11
  • !
    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.
