  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns15.hichina.com (120.76.107.42): read udp 46.225.38.91:37737->120.76.107.42:53: i/o timeout.

  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026081813 on dns16.hichina.com (120.76.107.51); 2026082509 on dns15.hichina.com (139.224.142.122), dns15.hichina.com (139.224.142.112), dns15.hichina.com (120.76.107.52), dns15.hichina.com (2408:4009:501::23), dns16.hichina.com (139.224.142.121), dns16.hichina.com (139.224.142.111); 2026082616 on dns15.hichina.com (47.118.199.212), dns16.hichina.com (39.96.153.41); 2026082617 on dns15.hichina.com (39.96.153.52), dns15.hichina.com (39.96.153.42), dns16.hichina.com (39.96.153.51), dns16.hichina.com (47.118.199.211), dns16.hichina.com (47.118.199.201), dns16.hichina.com (120.76.107.41), dns16.hichina.com (2408:4009:501::24); 2026082816 on dns15.hichina.com (47.118.199.202). 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

  • ✗
    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
  • ✗
    No DKIM keys published
    DKIM · _domainkey.ybx-emc.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: hzmx01.mxmail.netease.com, hzmx02.mxmail.netease.com
    #11
  • !
    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.
