Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), MX (3m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 1m; resolvers may use either.

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

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

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.
