Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-148.akam.net: "41824.11"; a1-148.akam.net: "41824.10"; a12-65.akam.net: "48878.33"; a12-65.akam.net: "48878.26"; a16-64.akam.net: "48878.27"; a16-64.akam.net: "48878.31"; a18-65.akam.net: "48878.26"; a18-65.akam.net: "48878.30"; a5-65.akam.net: "41824.9"; a5-65.akam.net: "41824.10"; a7-67.akam.net: "41824.7"; a7-67.akam.net: "41824.10". Hide or replace the version string.

SOA · retry 1h should be shorter than refresh 30m. Current values: refresh 30m, retry 1h, expire 14d, negative TTL 5m.

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.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-001bf601.gslb.pphosted.com, mxb-001bf601.gslb.pphosted.com, mx0a-001bf601.pphosted.com, mx0b-001bf601.pphosted.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits), selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

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 · These MX hosts publish no TLSA records, so mail to them is not protected by DANE: mx0a-001bf601.pphosted.com, mx0b-001bf601.pphosted.com.
