Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns2.zebi.nl. ns1.hzeeland.nl, ns1.zebi.nl, ns2.surfnet.nl, ns2.zebi.nl report NS ns1.hzeeland.nl ns1.zebi.nl ns2.surfnet.nl ns2.zebi.nl.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.zebi.nl: "9.18.49-1~deb12u2-Debian"; ns2.zebi.nl: "9.18.49-1~deb12u2-Debian". Hide or replace the version string.

  • !
    Signatures expire soon
    DNSSEC · The earliest signature expires at 2026-10-26 08:47 UTC (in 91h0m0s). Check that automatic re-signing works.
    #30
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 50 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 DKIM keys published
    DKIM · _domainkey.krantenbankzeeland.nl does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  • !
    Signatures expire in 91h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-26T08:47:03Z (in 91h0m0s). Check that re-signing works.
    #21
  • !
    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.
