Problems

  • ✗
    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: gtmcnc.midea.com.cn (58.252.101.8): dial tcp 58.252.101.8:53: i/o timeout; gtmct.midea.com.cn (202.104.30.87): dial tcp 202.104.30.87:53: i/o timeout; gtmnhcnc.midea.com.cn (157.122.158.5): dial tcp 157.122.158.5:53: i/o timeout; gtmnhct.midea.com.cn (218.13.19.5): dial tcp 218.13.19.5:53: i/o timeout.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: gtmhk.midea.com.cn, gtmpccw.midea.com.cn. gtmcnc.midea.com.cn, gtmct.midea.com.cn, gtmhk.midea.com.cn, gtmnhcnc.midea.com.cn, gtmnhct.midea.com.cn, gtmpccw.midea.com.cn report NS gtmcnc.midea.com.cn gtmct.midea.com.cn gtmhk.midea.com.cn gtmnhcnc.midea.com.cn gtmnhct.midea.com.cn gtmpccw.midea.com.cn.
    #7
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: gtmcnc.midea.com.cn: "9.16.33"; gtmct.midea.com.cn: "9.16.33"; gtmhk.midea.com.cn: "9.16.33"; gtmnhcnc.midea.com.cn: "9.16.33"; gtmnhct.midea.com.cn: "9.16.33"; gtmpccw.midea.com.cn: "9.16.33". Hide or replace the version string.

    Unusual SOA timers
    SOA · negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 3h, retry 1h, expire 7d, negative TTL 1m.
    #23
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1h; resolvers may use either.

Problems

  • !
    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
  • !
    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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxnh1.midea.com, mxsd1.midea.com, mxhk1.midea.com, mxhk2.midea.com
    #11
  • !
    Applies to 10% of mail
    DMARC · DMARC policy only applies to 10% of failing mail (pct=10). Raise pct to 100 once you are confident in your setup.
    #18
  • !
    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 159.138.38.120 -> ecs-159-138-38-120.compute.hwclouds-dns.com, 202.104.30.73 -> mail.chinamidea.com, 159.138.38.120 -> ecs-159-138-38-120.compute.hwclouds-dns.com, 159.138.38.120 -> ecs-159-138-38-120.compute.hwclouds-dns.com.
    #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.
