Nameservers in one network

Delegation · all IPv4 addresses are in 83.166.143.0/24; all IPv6 addresses are in 2001:1600::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
!

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: mx-mibc-fr-11.mailinblack.com

#11
!

Single MX host, no backup

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

#12
!

Addresses without reverse DNS

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 4.176.17.204 (mx-mibc-fr-11.mailinblack.com). Ask your hosting provider to set one.

#30
!

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.
