Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns2.wechat.com (240e:9f:c600::8): read udp [2a01:4f8:1c1c:eebf::1]:33447->[240e:9f:c600::8]:53: i/o timeout; ns4.wechat.com (61.135.196.3): read udp 46.225.38.91:38227->61.135.196.3:53: i/o timeout.

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.wechat.com (183.60.116.2): dial tcp 183.60.116.2:53: i/o timeout; ns1.wechat.com (112.90.13.140): dial tcp 112.90.13.140:53: i/o timeout; ns1.wechat.com (2402:4e00:c050:7a00::3): dial tcp [2402:4e00:c050:7a00::3]:53: i/o timeout; ns2.wechat.com (1.12.96.10): dial tcp 1.12.96.10:53: i/o timeout; ns3.wechat.com (120.204.7.98): dial tcp 120.204.7.98:53: i/o timeout.

    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d; retry 10m should be shorter than refresh 5m; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 5m, retry 10m, expire 1d, negative TTL 1d.

    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 DKIM keys published
    DKIM · _domainkey.wechat.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #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
  • !
    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.
