Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns4.teresto.net. ns1.teresto.net, ns2.teresto.net, ns3.teresto.net, ns4.teresto.net, pns.am-gruppe.de, pns2.am-gruppe.de report NS ns1.teresto.net ns2.teresto.net ns3.teresto.net ns4.teresto.net pns.am-gruppe.de pns2.am-gruppe.de.

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.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 5m; resolvers may use either.

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: generali-com.mail.protection.outlook.com, generali-com.mail.protection.outlook.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.
