    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.qq.com (183.60.116.2): dial tcp 183.60.116.2:53: i/o timeout; ns1.qq.com (112.90.13.140): dial tcp 112.90.13.140:53: i/o timeout; ns1.qq.com (2402:4e00:c050:7a00::3): dial tcp [2402:4e00:c050:7a00::3]:53: i/o timeout; ns2.qq.com (1.12.96.10): dial tcp 1.12.96.10:53: i/o timeout; ns2.qq.com (240e:974:e600:3ee::2): dial tcp [240e:974:e600:3ee::2]:53: i/o timeout; ns3.qq.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 10m.

    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 DKIM keys published
    DKIM · _domainkey.weiyun.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: smtp.weiyun.com

    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
