Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: alexandra.ns.cloudflare.com: "2026.10.2"; sterling.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

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: mailstream-east.mxrecord.io, mailstream-west.mxrecord.io, mailstream-central.mxrecord.mx, mailstream-eu1.mxrecord.io

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits). Rotate to a 2048-bit key.

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 172.65.213.128 (mailstream-east.mxrecord.io), 172.65.220.210 (mailstream-west.mxrecord.io), 172.65.64.78 (mailstream-central.mxrecord.mx), 172.65.245.214 (mailstream-eu1.mxrecord.io). Ask your hosting provider to set one.

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.
