    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns-f.lmz-bw.de (2a03:f80:49:151:236:17:212:53): read udp [2a01:4f8:1c1c:eebf::1]:47775->[2a03:f80:49:151:236:17:212:53]:53: i/o timeout; dns-z.lmz-bw.de (2a02:418:6a04:178:209:52:186:53): read udp [2a01:4f8:1c1c:eebf::1]:49215->[2a02:418:6a04:178:209:52:186:53]:53: i/o timeout.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: dns1.belwue.de. dns-f.lmz-bw.de, dns-z.lmz-bw.de, dns1.belwue.de, dns3.belwue.de report NS dns-f.lmz-bw.de dns-z.lmz-bw.de dns3.belwue.de.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.belwue.de: "PowerDNS Authoritative Server 4.5.5 (built Dec 8 2022 18:24:18 by root@a309361b6303)"; dns3.belwue.de: "PowerDNS Authoritative Server 4.5.5 (built Dec 8 2022 18:24:18 by root@a309361b6303)". Hide or replace the version string.

    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.

  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: email (1024 bits), selector1 (1024 bits), selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
