    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: vip3.alidns.com (glue 121.40.6.163, 140.205.1.5, 170.33.32.210, 170.33.73.26, 170.33.80.10, 2408:4009:500::3, 39.103.26.212, 47.108.36.163, 47.116.84.178, 8.129.152.245, 8.212.93.3, zone 8.212.93.3, 170.33.73.26, 140.205.1.5, 170.33.80.10, 170.33.32.210, 2408:4009:500::3); vip4.alidns.com (glue 121.40.6.164, 140.205.1.6, 170.33.32.211, 170.33.73.27, 170.33.80.11, 2408:4009:500::4, 39.103.26.213, 47.108.36.164, 47.116.84.179, 8.129.152.246, 8.212.93.4, zone 140.205.1.6, 8.212.93.4, 170.33.80.11, 170.33.32.211, 170.33.73.27, 2408:4009:500::4).

    Serials differ
    SOA · The nameservers serve different versions of the zone: 2015021216 on vip3.alidns.com (170.33.73.26), vip4.alidns.com (170.33.80.11); 2026081712 on vip4.alidns.com (170.33.32.211); 2026081716 on vip4.alidns.com (170.33.73.27); 2026081810 on vip3.alidns.com (8.212.93.3), vip4.alidns.com (140.205.1.6), vip4.alidns.com (2408:4009:500::4); 2026082415 on vip3.alidns.com (140.205.1.5), vip3.alidns.com (2408:4009:500::3); 2026082516 on vip3.alidns.com (170.33.80.10), vip3.alidns.com (170.33.32.210), vip4.alidns.com (8.212.93.4). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    Unusual SOA timers
    SOA · expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1h, retry 20m, expire 1d, negative TTL 10m.
    #23
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: google (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
