Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-157.akam.net: "41824.7"; a1-157.akam.net: "41824.8"; a10-65.akam.net: "48878.33"; a10-65.akam.net: "48878.31"; a28-64.akam.net: "48878.31"; a28-64.akam.net: "48878.27"; a3-65.akam.net: "41824.11"; a4-66.akam.net: "48878.32"; a4-66.akam.net: "48878.30"; a9-65.akam.net: "41824.7"; a9-65.akam.net: "41824.4". Hide or replace the version string.

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

DNSSEC · DNSKEY signatures expire at 2026-10-24T02:15:37Z (in 53h0m0s). Check that re-signing works.

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.

TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
