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.
- • No SPF record (v=spf1) published on the domain.
- • 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.

About Lycée Victor Grignard
Lycée Victor Grignard is a public secondary school located in Cherbourg-en-Cotentin, in the Manche department, in the Normandy region of France. Its name pays tribute to Victor Grignard, a French chemist awarded the Nobel Prize in Chemistry in the early twentieth century, a choice that reflects a historical orientation toward scientific disciplines. The institution is part of the local educational network of the Cherbourg area, which includes several public schools serving the formerly separate communes now combined within the new commune of Cherbourg-en-Cotentin.
The school enrolls students in the upper cycle of secondary education, offering a path leading to the baccalauréat as well as, depending on the tracks available, technological or vocational training. Its scope of activity covers general education and, where applicable, specializations related to the sciences, in keeping with the legacy of the name it bears. It also takes part in guiding students through their academic and career orientation, in coordination with other educational institutions in the area and the relevant academic authorities.
Situated in a port and industrial city with a strong tradition of technological and maritime activity, Lycée Victor Grignard holds a place within the network of secondary schools in the Manche department under the Normandy education authority. At its own level, it contributes to educating younger generations across the Cotentin region, relying on national curricula set by the Ministry of Education and on resources provided by the local authorities responsible for school infrastructure.
