Strengthen the DMARC policy
Rejects mail that fails DMARC, the strongest protection against spoofing. There is no report address yet: set one up first (see the DMARC reporting fix) so you can confirm your legitimate mail passes before enforcing. Changes: Subdomains move one step, from sp=none to sp=quarantine.
_dmarc.free.fr
Some DNS providers want just “_dmarc” here.
v=DMARC1; p=reject; sp=quarantine; adkim=r; aspf=r
v=DMARC1;p=quarantine;adkim=r;aspf=r;sp=none
How to apply it
- Sign in where your domain’s DNS is managed. This is often where you bought the domain, such as Cloudflare, GoDaddy or Namecheap.
- Find the existing TXT record with that name and replace its value.
- Save, then come back and re-check. DNS changes can take up to a few hours to show.
All checks
MXCan servers find your inbox?No issues foundPass
Nothing to report.
SPFWho may send as you?SPF ends in softfail (~all)Info
- Info: SPF ends in softfail (~all)
"~all" is common and works well with DMARC. "-all" is stricter; switch when you are sure every sender is listed.
DKIMAre your emails signed?No DKIM key found for the common selectorsNeeds attention
- Warning: No DKIM key found for the common selectors
None of the 47 selectors probed under free.fr publish a DKIM key. DNS cannot list selectors, so a key under a custom selector may exist: find the s= value in the DKIM-Signature header of a message you sent and check that selector. If DKIM is not set up, enable it at each service that sends mail for free.fr.
DMARCWhat happens to fakes?Subdomain policy is weaker than the domain policyNeeds attention
- Warning: Subdomain policy is weaker than the domain policy
sp=none is weaker than p=quarantine, so attackers can spoof any subdomain of free.fr (for example billing.free.fr) even though the main domain is protected.
How to fix this - Warning: No DMARC aggregate report address
Without a rua address you receive no aggregate reports, so you cannot see who sends as your domain or safely tighten the policy.
How to fix this - Info: DMARC policy is quarantine; consider reject
Failing mail goes to spam rather than being refused. When reports show no legitimate failures, reject gives the strongest protection.

AlignmentDoes it match your From?No issues foundPass
Nothing to report.
BIMICan inboxes show your logo?No BIMI recordInfo
- Info: No BIMI record
No BIMI record at default._bimi.free.fr. BIMI is optional: it shows your logo next to your mail in supporting inboxes once DMARC is enforced.
How to fix this
MTA-STSIs mail to you encrypted?No MTA-STS recordInfo
- Info: No MTA-STS record
No MTA-STS record at _mta-sts.free.fr. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.
How to fix this
TLS-RPTWill you hear about failures?No TLS-RPT recordInfo
- Info: No TLS-RPT record
No TLS reporting record at _smtp._tls.free.fr. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

Other fixes
Set up a DMARC report addressinstruction
Without a rua address nobody receives aggregate reports, so you cannot see who sends as free.fr or tell when it is safe to tighten the policy. Adding reporting does not change how receivers treat your mail.
Applies to: _dmarc.free.fr
- Get an address that collects DMARC aggregate reports: add free.fr to MailVakt to receive one, or sign up with any DMARC report service. 2. Edit the TXT record at _dmarc.free.fr and add rua=mailto:<that address>, keeping every other tag (p=quarantine, sp=none) as it is. 3. A report service on another domain must authorize free.fr; most publish that record for you.
Publish the MTA-STS recordTXT
Tells sending servers that free.fr publishes an MTA-STS policy at https://mta-sts.free.fr/.well-known/mta-sts.txt. Change the id whenever the policy file changes.
_mta-sts.free.fr
Some DNS providers want just “_mta-sts” here.
v=STSv1; id=202610040212
Host the MTA-STS policy filepolicy-file
Serve this file over HTTPS with a valid certificate for mta-sts.free.fr. It lists your MX hosts and starts in testing mode; switch to mode: enforce once TLS-RPT reports show no failures.
https://mta-sts.free.fr/.well-known/mta-sts.txt
version: STSv1 mode: testing mx: mx1.free.fr mx: mx2.free.fr max_age: 604800
Set up a TLS report addressinstruction
Sending servers will report TLS failures when delivering to free.fr, which you need before enforcing MTA-STS. The address must accept TLS reports; a DMARC report address does not necessarily do so.
Applies to: _smtp._tls.free.fr
- Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@free.fr, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.free.fr with the value v=TLSRPTv1; rua=mailto:<that address>.
Prepare BIMIinstruction
BIMI shows your logo next to messages in supporting inboxes, but only for mail that passes DMARC under an enforced policy.
Applies to: default._bimi.free.fr
- Enforce DMARC first: p=quarantine or p=reject at 100% (no pct below 100). 2. Convert your logo to an SVG Tiny PS file and host it over HTTPS, for example https://free.fr/bimi/logo.svg. 3. For Gmail and Apple Mail, obtain a VMC or CMC certificate for the logo. 4. Publish a TXT record at default._bimi.free.fr with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
