Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: iris.ns.cloudflare.com: "2026.10.2"; randy.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.

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

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: inbound-mx1.mailchimpapp.net

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

MX · MX records must point to a host name with A/AAAA records, not to a CNAME: inbound-mx1.mailchimpapp.net -> yjgct5wthn9n.fips.yxbq.mail-manager-smtp.amazonaws.com

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.
