Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: s-1923.awsdns-48.co.uk; only in the zone: ns-1923.awsdns-48.co.uk. ns-1015.awsdns-62.net, ns-1142.awsdns-14.org, ns-1923.awsdns-48.co.uk, ns-319.awsdns-39.com report NS ns-1015.awsdns-62.net ns-1142.awsdns-14.org ns-1923.awsdns-48.co.uk ns-319.awsdns-39.com.

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), NS (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 2m; 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.

DKIM · These keys could not be parsed, so signatures made with them will fail: google (public key is not valid base64).

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

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.
