Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: v6ns1.dnspod.net, v6ns2.dnspod.net; only in the zone: ns3.dnsv4.com, ns4.dnsv4.com. ns3.dnsv4.com, ns4.dnsv4.com, v6ns1.dnspod.net, v6ns2.dnspod.net report NS ns3.dnsv4.com ns4.dnsv4.com.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.dnsv4.com: "DNSPod AUTHORITY DNS 7.3.2512.01"; ns4.dnsv4.com: "DNSPod AUTHORITY DNS 7.3.2512.01"; v6ns1.dnspod.net: "DNSPod AUTHORITY DNS 7.3.2512.01"; v6ns2.dnspod.net: "DNSPod AUTHORITY DNS 7.3.2512.01". Hide or replace the version string.

  • !
    Unusual SOA timers
    SOA · negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1h, retry 3m, expire 14d, negative TTL 3m.
    #23
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (10s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxbiz1.qq.com, mxbiz2.qq.com
    #11
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 103.86.78.2 (mxbiz1.qq.com), 103.86.78.3 (mxbiz1.qq.com), 43.154.252.16 (mxbiz2.qq.com), 43.154.252.202 (mxbiz2.qq.com). Ask your hosting provider to set one.
    #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.
