Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: dns.oost-vlaanderen.be. dns.oost-vlaanderen.be, ns1.belnet.be, ns2.belnet.be, ns3.belnet.be report NS dns.oost-vlaanderen.be ns1.belnet.be ns2.belnet.be ns3.belnet.be.

  • !
    Signatures expire soon
    DNSSEC · The earliest signature expires at 2026-10-28 01:12 UTC (in 138h0m0s). Check that automatic re-signing works.
    #30
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 1-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.

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits). Rotate to a 2048-bit key.

  • !
    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.
