Problems

!

No IPv6

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

#13
!

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

✗

No DMARC record

DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

#5
✗

No DKIM keys published

DKIM · _domainkey.teaser.fr does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

#7
!

Uses deprecated ptr mechanism

SPF · The ptr mechanism in SPF records is deprecated due to performance issues and should be avoided.

#1
!

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-domain.netcourrier.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
!

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.
