    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns2.hpe.com (glue 16.2.148.110, zone 16.2.141.20); ns5.hpe.com (glue 16.2.141.20, zone 16.2.148.110); ns7.hpe.com (glue 192.170.11.194, zone 16.2.148.110); ns8.hpe.com (glue 192.170.12.194, zone 16.2.132.115). Update the glue at your registrar.

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

  • !
    Unusual SOA timers
    SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 28d, negative TTL 15m.
    #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 DKIM keys published
    DKIM · _domainkey.sgi.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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxb-002e3701.gslb.pphosted.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.
