Published record
v=DMARC1; p=noneWhat 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.
- • At least one valid DKIM key published.
- • 1024-bit DKIM RSA key: still tolerated but below the state of the art — rotate to 2048 bits. (dkim : 1024 bits)
- • 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 professionnel Denis Papin
The Lycée professionnel Denis Papin is a public secondary education institution located in Romorantin-Lanthenay, in the Loir-et-Cher department, in the Centre-Val de Loire region of France. It is named after Denis Papin, a French physicist and inventor originally from this town, in tribute to his contributions to science and technology. The institution is part of the network of vocational high schools under the French Ministry of National Education, whose purpose is to prepare students for vocational education diplomas, such as the vocational aptitude certificate (CAP) and the vocational baccalaureate, across various technological and industrial fields.
Situated in Romorantin-Lanthenay, a town with a historically strong industrial and craft tradition, the school primarily welcomes students from the local training area and surrounding municipalities in Loir-et-Cher. Its geographic location makes it a local provider of initial vocational training in this territory, contributing to the departmental educational offer alongside other schools in the region. The institution provides pedagogical support tailored to the specificities of vocational education, combining general and technical or practical instruction depending on the programs offered.
The Lycée Denis Papin operates within the general mission of the public education service, namely the transmission of knowledge, preparation for working life and further studies, and the professional integration of trained young people. Like all French vocational high schools, it collaborates with local economic partners to organize work-based training periods, thereby fostering the connection between academic training and workplace realities. The institution also participates in the educational and cultural life of its host territory.
