SPF · DKIM · DMARC — 36/50

Durcissement

DNS & transport — 10/50

✓ SPF 15/15

SPF present with -all (hardfail) — strongest policy. Uses 6/10 DNS lookups.

v=spf1 include:_spfstd_sccc.laposte.fr include:_spfmm_sccc.laposte.fr include:_spfal_sccc.laposte.fr include:_spftmp_sccc.laposte.fr  include:mail.zendesk.com mx -all

~ DMARC 9/20

DMARC present — p=none, sp=none.

v=DMARC1; p=none; pct=100; rua=mailto:laposte.rua@emailsecurity.merox.io

→ Strengthen DMARC: raise p to quarantine, then reject, once reports look clean.

TXT _dmarc.laposte.fr  v=DMARC1; p=reject; sp=reject; rua=mailto:dmarc@laposte.fr

~ DKIM 12/15

DKIM key found (selector2) but looks 1024-bit or weaker: selector2.
```
selector2
```
→ Rotate to a 2048-bit DKIM key at your provider.
✗ CAA 0/10

No CAA records — any certificate authority can issue certs for this domain.
→ Restrict which CAs may issue certificates for your domain (create the security@ mailbox or alias to receive iodef reports).
```
CAA @  0 issue "letsencrypt.org"
0 iodef "mailto:security@laposte.fr"
```
✗ DANE/TLSA 0/5

No DANE/TLSA records on the MX (rpi0i753.laposte.fr, rpi0i751.laposte.fr, rpi0i693.laposte.fr, rpi0i691.laposte.fr).

→ DANE requires DNSSEC. Once the zone is signed, publish a TLSA record at _25._tcp.<mail-server> for each MX host, matching the certificate it serves on port 25.
✗ MTA-STS 0/10

No MTA-STS record — inbound mail can be downgraded to cleartext.
→ Publish the MTA-STS TXT record AND serve the policy file at https://mta-sts.laposte.fr/.well-known/mta-sts.txt (set id to a fresh YYYYMMDDnn value).
```
TXT _mta-sts.laposte.fr  v=STSv1; id=REPLACE_WITH_DATE
```
✗ TLS-RPT 0/5

No TLS-RPT record — you won't be told when mail TLS fails.
→ Publish a TLS-RPT record to receive reports of mail TLS failures.
```
TXT _smtp._tls.laposte.fr  v=TLSRPTv1; rua=mailto:tls-reports@laposte.fr
```
✗ BIMI 0/5

No BIMI record found.

→ BIMI requires DMARC at quarantine/reject first. Then publish a BIMI record pointing to an SVG Tiny PS logo (l=) and ideally a VMC certificate (a=).
✗ DNSSEC 0/10

DNSSEC not detected.

→ Enable DNSSEC at your DNS host, then add the DS record at your registrar to complete the chain of trust.
✓ TLS web 10/5

HTTPS active — TLSv1.3.
