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.

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: chru37.in.tmes.trendmicro.eu
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  • !
    Applies to 1% of mail
    DMARC · DMARC policy only applies to 1% of failing mail (pct=1). Raise pct to 100 once you are confident in your setup.

    Signatures expire in 166h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-29T00:00:00Z (in 166h0m0s). Check that re-signing works.

  • !
    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.
