Not signed

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.

Very low TTLs

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

Policy not reachable

TLS · The MTA-STS record exists but the policy could not be fetched, so senders ignore MTA-STS: Get "https://mta-sts.gulp.de/.well-known/mta-sts.txt": dial tcp: lookup mta-sts.gulp.de on 127.0.0.53:53: no such host.

!

Not enabled

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

1024-bit DKIM key
