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: ns1.sj1.northsky.com (64.136.25.253): dial tcp 64.136.25.253:53: connect: connection refused; ns2.sj1.northsky.com (64.136.44.123): dial tcp 64.136.44.123:53: connect: connection refused.
    #19
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.sj1.northsky.com (64.136.25.253), ns2.sj1.northsky.com (64.136.44.123).
    #20
  • !
    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d; retry 5m should be shorter than refresh 5m. Current values: refresh 5m, retry 5m, expire 14d, negative TTL 5m.
    #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 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
  • !
    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: mx-ws.dca.untd.com, mx-ws.vgs.untd.com
    #11
  • !
    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.
