Problems

  • !
    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.
    #4
  • !
    Signatures expire in 5h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-22T02:00:00Z (in 5h0m0s). Check that re-signing works.
    #21
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), k1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Broad IP ranges
    SPF · These ranges authorize tens of thousands of addresses or more: ip4:40.92.0.0/15, ip4:52.100.0.0/15. Check that you really own and send from all of them.
    #27
  • !
    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.
