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 (1m), AAAA (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1h; resolvers may use either.

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

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: mx.xcancel.com -> mx.emiliendevos.be

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: s2 (1024 bits). Rotate to a 2048-bit key.

DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:postmaster@unixfox.eu (needs xcancel.com._report._dmarc.unixfox.eu). Ask the report provider to publish the record, or check the address.

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 152.70.188.178 (mx.xcancel.com), 152.67.94.22 (mx.xcancel.com). Ask your hosting provider to set one.

TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.

TLS · These MX hosts are not listed in the MTA-STS policy (mx: mx.emiliendevos.be): mx.xcancel.com. This will break delivery once the policy is enforced.
