    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.digitalocean.com (glue 172.64.52.210, zone 172.64.52.210, 2606:4700:52::ac40:34d2); ns2.digitalocean.com (glue 172.64.53.21, zone 172.64.53.21, 2606:4700:5a::ac40:3515); ns3.digitalocean.com (glue 172.64.49.209, zone 172.64.49.209, 2606:4700:52::ac40:31d1). Update the glue at your registrar.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.digitalocean.com: "2026.10.8"; ns2.digitalocean.com: "2026.10.8"; ns3.digitalocean.com: "2026.10.8". Hide or replace the version string.

    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

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    No DKIM keys published
    DKIM · _domainkey.portableapps.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: mx1.emailsrvr.com, mx2.emailsrvr.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.
