DNSSEC

Signed, but no DS at parent

Found

DNSKEY records: Yes (4)
DS at parent: No

Signed, but no DS at parent

The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.

Not configured

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.

✓ Reports enabled #35

TLS reports are sent to: mailto:tlsrpt@zwevegem.uriports.com

Not used

No MX host publishes TLSA records. DANE lets senders verify your mail server's certificate through DNSSEC; it requires DNSSEC on the MX host's zone.
