Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.combell.eu. ns1.combell.eu, ns3.combell.net, ns4.combell.net report NS ns1.combell.eu ns3.combell.net ns4.combell.net.

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 5 iterations and a 4-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 (1m), MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m; resolvers may use either.

Problems

  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:dmarc@anandan.nl (needs huismarseille.nl._report._dmarc.anandan.nl). Ask the report provider to publish the record, or check the address.
    #29
  • !
    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.
