Problems

!

No IPv6

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

#13
!

Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.sfrbusinessteam.fr: "Microsoft DNS 6.1.7601 (1DB15F75)"; ns2.sfrbusinessteam.fr: "Microsoft DNS 6.1.7601 (1DB15F75)". Hide or replace the version string.

#17
!

Not signed

DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

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'.

#4
!

Not enabled

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

#8
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: chatelguyon.in.tmes.trendmicro.eu

#11
!

1024-bit DKIM key

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (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.
