Problems

  • !
    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.
    #31
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (4m15s). Low TTLs are useful just before a planned change.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    Weak DKIM key
    DKIM · RSA keys shorter than 1024 bits can be cracked and are ignored by receivers (RFC 8301): dkim (384 bits). Rotate to a 2048-bit key.
    #23
  • !
    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 178.22.57.140 -> hosting204.exonet.nl, 2a00:1e28:3:1532::1 -> hosting204.exonet.nl.
    #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.
