    Unusual SOA timers
    SOA · refresh 15m is outside 20m–1d; retry 15m should be shorter than refresh 15m; expire 30m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 30m must be longer than refresh + retry; negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 15m, retry 15m, expire 30m, negative TTL 1m.

Problems

  • ✗
    No DKIM keys published
    DKIM · _domainkey.play.google.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

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

  • !
    Not configured
    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.
