Problems

  • ✗
    TLD not in the root zone
    Registration · .com is not delegated in the root zone, so names under it can't be resolved on the public internet.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: a4-67.akam.net. a1-90.akam.net, a10-67.akam.net, a3-65.akam.net, a4-67.akam.net, a8-64.akam.net, a9-64.akam.net, corp-eqix-ch4-dnsxs-001.walgreens.com, corp-eqix-dc5-dnsxs-001.walgreens.com report NS a1-90.akam.net a10-67.akam.net a3-65.akam.net a4-67.akam.net a8-64.akam.net a9-64.akam.net corp-eqix-ch4-dnsxs-001.walgreens.com corp-eqix-dc5-dnsxs-001.walgreens.com.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-90.akam.net: "41824.8"; a10-67.akam.net: "48878.33"; a10-67.akam.net: "48878.31"; a3-65.akam.net: "41824.6"; a3-65.akam.net: "41824.8"; a4-67.akam.net: "48878.31"; a4-67.akam.net: "48878.29"; a8-64.akam.net: "48878.30"; a8-64.akam.net: "48878.33"; a9-64.akam.net: "41824.10"; a9-64.akam.net: "41824.5". 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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1h; resolvers may use either.

Problems

  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    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: usb-smtp-inbound-1.mimecast.com, usb-smtp-inbound-2.mimecast.com
    #11
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    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.
