Registration · The registration expires on 2026-11-18. Make sure it is renewed.

DNSSEC · SHA-1 based algorithms are deprecated and rejected by some validators: RSASHA1-NSEC3-SHA1 (7). Roll over to ECDSAP256SHA256 (13).

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

MX · The following MX hosts could not be resolved to IPv6 addresses: mx-mibc-fr-05.mailinblack.com

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 51.103.112.132 (mx-mibc-fr-05.mailinblack.com). Ask your hosting provider to set one.

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.
