Published record
v=DMARC1;p=none;What this means
- • Policy p=none: monitoring only, no unauthenticated message is blocked.
- • No rua address: aggregate reports are not collected, which makes steering the hardening impossible.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • No DKIM key found on the common selectors (the domain may use non-standard selectors).
- • No MTA-STS (_mta-sts): inbound SMTP connections remain exposed to TLS downgrade. Recommended alongside DMARC.
- • No TLS-RPT (_smtp._tls): the TLS failures encountered by senders are not reported.

About Lycée polyvalent Jean Moulin
Lycée polyvalent Jean Moulin is a public secondary education institution located in Le Blanc-Mesnil, a municipality in Seine-Saint-Denis, in the Île-de-France region of France. Under the authority of the French Ministry of Education and part of the Créteil academic district, it enrolls students in general, technological, and vocational programs, which gives it the designation of a "lycée polyvalent" (multi-track upper secondary school). Its name honors Jean Moulin, a prominent figure of the French Resistance, a common practice in the naming of French public schools.
The institution is part of the local educational network of Le Blanc-Mesnil, a suburban town within the Seine-Saint-Denis department. It contributes to the secondary education offer of its catchment area by providing a diversified curriculum that allows students to pursue different pathways after completing lower secondary school (collège), whether in general, technological, or vocational tracks. This coexistence of multiple tracks within a single institution characterizes so-called "polyvalent" lycées, as distinct from purely general and technological lycées or strictly vocational ones.
The scope of activity of Lycée Jean Moulin centers on its teaching mission, but also extends to guiding students in their educational and career orientation, preparing them for national examinations, and supporting their transition toward higher education or professional life. Like any public secondary institution in France, it operates under the authority of a head of institution and relies on a pedagogical and administrative team responsible for implementing nationally defined curricula. It also participates in local educational life through cooperation with local authorities and institutional partners in the education sector.
