Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns-1819.awsdns-35.co.uk, ns-311.awsdns-38.com; only in the zone: ns3-08.azure-dns.org, ns4-08.azure-dns.info. ns-1819.awsdns-35.co.uk, ns-311.awsdns-38.com report NS ns-1079.awsdns-06.org ns-1819.awsdns-35.co.uk ns-311.awsdns-38.com ns-982.awsdns-58.net. ns1-08.azure-dns.com, ns2-08.azure-dns.net, ns3-08.azure-dns.org, ns4-08.azure-dns.info report NS ns1-08.azure-dns.com ns2-08.azure-dns.net ns3-08.azure-dns.org ns4-08.azure-dns.info.

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns4-08.azure-dns.info: "Knot DNS 3.1.2.1770717641.d6b376aff". 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.

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

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: mx2.iiinnn.com, mx3.iiinnn.com, mx4.iiinnn.com, mx5.iiinnn.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (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.
