Registration · The registration expires on 2026-11-08. Make sure it is renewed.

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

SOA · negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 4h, retry 15m, expire 7d, negative TTL 3m.

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

MX · The following MX hosts could not be resolved to IPv6 addresses: mailjet-com.mail.protection.outlook.com

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

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

BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
