  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.broadspeed.de: "2026.10.8"; ns.broadspeed.eu: "2026.10.8"; ns.broadspeed.io: "2026.10.8"; ns.broadspeed.it: "2026.10.8". Hide or replace the version string.

    Signatures expire soon
    DNSSEC · The earliest signature expires at 2026-10-26 19:34 UTC (in 116h0m0s). Check that automatic re-signing works.
    #30
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 0 iterations and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

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
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.kulturkaufhaus.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx24a.antispameurope.com, mx24b.antispameurope.com, mx24c.antispameurope.com

    Signatures expire in 116h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-26T19:34:48Z (in 116h0m0s). Check that re-signing works.
    #21
  • !
    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 83.246.65.100 -> nlb01-hz2.hornetsecurity.com.65.246.83.in-addr.arpa.
    #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.
