    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026081813 on dns10.hichina.com (2408:4009:501::18); 2026082509 on dns10.hichina.com (120.76.107.41); 2026082616 on dns10.hichina.com (120.76.107.51), dns10.hichina.com (139.224.142.111), dns10.hichina.com (39.96.153.41), dns9.hichina.com (47.118.199.212), dns9.hichina.com (120.76.107.52), dns9.hichina.com (47.118.199.202), dns9.hichina.com (39.96.153.52), dns9.hichina.com (139.224.142.112), dns9.hichina.com (39.96.153.42), dns9.hichina.com (2408:4009:501::17); 2026082617 on dns10.hichina.com (47.118.199.211), dns10.hichina.com (39.96.153.51), dns9.hichina.com (120.76.107.42); 2026082709 on dns10.hichina.com (139.224.142.121), dns9.hichina.com (139.224.142.122); 2026082815 on dns10.hichina.com (47.118.199.201). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

  • !
    Unusual SOA timers
    SOA · expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1h, retry 20m, expire 1d, negative TTL 10m.
    #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.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No DKIM keys published
    DKIM · _domainkey.zhilingjia.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    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
  • !
    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), 43.154.252.202 (mxbiz2.qq.com), 43.154.252.16 (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.
