  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns16.hichina.com (2408:4009:501::24): read udp [2a01:4f8:1c1c:eebf::1]:53944->[2408:4009:501::24]:53: i/o timeout.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 2010051309 on dns16.hichina.com (139.224.142.121); 2026082509 on dns16.hichina.com (120.76.107.51); 2026082616 on dns15.hichina.com (39.96.153.42), dns15.hichina.com (139.224.142.112), dns15.hichina.com (47.118.199.212), dns15.hichina.com (120.76.107.42), dns15.hichina.com (139.224.142.122), dns16.hichina.com (120.76.107.41), dns16.hichina.com (47.118.199.201); 2026082617 on dns15.hichina.com (39.96.153.52), dns15.hichina.com (120.76.107.52), dns15.hichina.com (2408:4009:501::23), dns16.hichina.com (39.96.153.51), dns16.hichina.com (39.96.153.41); 2026082709 on dns16.hichina.com (139.224.142.111); 2026082815 on dns15.hichina.com (47.118.199.202), dns16.hichina.com (47.118.199.211). 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 DKIM keys published
    DKIM · _domainkey.pdoca.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: mail.pdoca.com
    #11
  • !
    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.
