Problems

  • !
    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.rocmn.nl (glue 194.171.158.1, 2001:610:518:158::1, zone 194.171.158.1). Update the glue at your registrar.
    #8
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 5-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

  • ✗
    Weak DKIM key
    DKIM · RSA keys shorter than 1024 bits can be cracked and are ignored by receivers (RFC 8301): pm (768 bits). Rotate to a 2048-bit key.
    #23
  • !
    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
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    Signatures expire in 92h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-26T11:58:43Z (in 92h0m0s). 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.
