    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026102102 on ns2.ovea.com (79.143.240.9), ns2.ovea.com (2a01:678::9), ns3.ovea.com (79.143.240.10), ns3.ovea.com (2a01:678::10); 2026102201 on ns1.ovea.com (79.143.240.8), ns1.ovea.com (2a01:678::8), ns4.ovea.com (79.143.245.187), ns4.ovea.com (2a01:67a:0:1::187). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    13 DNS lookups, over the limit of 10
    SPF · SPF record needs 13 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.

    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: vade-mx-fr01.hornetsecurity.com, vade-mx-fr02.hornetsecurity.com, vade-mx-eu-fallback01.hornetsecurity.com, vade-mx-eu-fallback02.hornetsecurity.com

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

    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.
