    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026081813 on dns17.hichina.com (120.76.107.60), dns18.hichina.com (2408:4009:501::26); 2026082509 on dns17.hichina.com (139.224.142.110), dns17.hichina.com (120.76.107.40), dns17.hichina.com (2408:4009:501::25), dns18.hichina.com (139.224.142.98), dns18.hichina.com (120.76.107.61), dns18.hichina.com (120.76.107.38); 2026082616 on dns17.hichina.com (47.118.199.220), dns17.hichina.com (47.118.199.200), dns18.hichina.com (47.118.199.198), dns18.hichina.com (39.96.153.61), dns18.hichina.com (39.96.153.38); 2026082617 on dns17.hichina.com (39.96.153.60), dns17.hichina.com (39.96.153.40); 2026082709 on dns17.hichina.com (139.224.142.100), dns18.hichina.com (139.224.142.108); 2026082815 on dns18.hichina.com (47.118.199.222). 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 DKIM keys published
    DKIM · _domainkey.intcomedical.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
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 52.101.137.2 (intcomedical-com.mail.protection.outlook.com), 2a01:111:f403:cc09::1 (intcomedical-com.mail.protection.outlook.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.
