Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns2.reedelsevier.com (glue 198.176.82.98, zone 198.176.82.118); ns3.reedelsevier.com (glue 198.176.82.101, zone 198.176.84.118). Update the glue at your registrar.

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

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 (59s). 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.

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

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 IP addresses: thelancet.com.inbound10.mxlogic.net, thelancet.com.inbound10.mxlogicmx.net

MX · The following MX hosts could not be resolved to IPv6 addresses: thelancet.com.inbound10.mxlogic.net, thelancet.com.inbound10.mxlogicmx.net

DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:dmarc-a@elsevier.com (needs thelancet.com._report._dmarc.elsevier.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.
