    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns6.ns35.de (2a01:4f8:c17:4781::2): read udp [2a01:4f8:1c1c:eebf::1]:33209->[2a01:4f8:c17:4781::2]:53: i/o timeout; ns8.ns35.de (2001:4178:5:111:85:236:38:58): read udp [2a01:4f8:1c1c:eebf::1]:46084->[2001:4178:5:111:85:236:38:58]:53: i/o timeout.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns5.ns35.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 10 2026 11:52:06 by root@bh-centos-7.dev.cpanel.net)"; ns6.ns35.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 10 2026 11:52:06 by root@bh-centos-7.dev.cpanel.net)"; ns7.ns35.de: "PowerDNS Authoritative Server 5.1.4 (built Aug 9 2026 23:00:00 by pbuilder@bh-ubuntu-24.dev.cpanel.net)"; ns8.ns35.de: "PowerDNS Authoritative Server 5.1.4 (built Aug 9 2026 23:00:00 by pbuilder@bh-ubuntu-24.dev.cpanel.net)". 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.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • !
    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
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 2001:608:e00:72::40:0 (hsg-greifswald-leichtathletik.de). Ask your hosting provider to set one.
    #30
  • !
    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.
