    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026081813 on dns3.hichina.com (120.76.107.43), dns3.hichina.com (2408:4009:501::11), dns4.hichina.com (120.76.107.54), dns4.hichina.com (120.76.107.44), dns4.hichina.com (2408:4009:501::12); 2026082509 on dns3.hichina.com (120.76.107.63); 2026082616 on dns3.hichina.com (139.224.142.113), dns3.hichina.com (47.118.199.203), dns4.hichina.com (47.118.199.214), dns4.hichina.com (39.96.153.44), dns4.hichina.com (47.118.199.204), dns4.hichina.com (139.224.142.124), dns4.hichina.com (139.224.142.114); 2026082617 on dns3.hichina.com (39.96.153.63), dns3.hichina.com (39.96.153.43), dns3.hichina.com (47.118.199.213), dns4.hichina.com (39.96.153.54); 2026082709 on dns3.hichina.com (139.224.142.123). 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 SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #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: mx1.qiye.aliyun.com, mx2.qiye.aliyun.com, mx3.qiye.aliyun.com
    #11
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 47.246.167.188 (mx1.qiye.aliyun.com), 47.246.137.47 (mx3.qiye.aliyun.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.
