Published record
v=DMARC1; p=quarantine;What this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • 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 Collège Langevin-Wallon
Collège Langevin-Wallon is a public lower secondary school located in France, in the commune of Grenay, in the Pas-de-Calais department. Its name pays tribute to Paul Langevin and Henri Wallon, two French intellectual figures associated with reflection on the democratization of education, whose work notably inspired reforms of the national education system. This naming places the institution within a pedagogical tradition attached to the values of the republican school and equal opportunity.
Situated within the territorial context of the Pas-de-Calais mining basin, an area marked by a distinctive industrial and social history, the school forms part of the network of public educational institutions responsible for schooling young people from the commune of Grenay and surrounding localities. It falls under the French academic organization, under the authority of the ministry responsible for national education, and operates according to the principles and curricula defined nationally for lower secondary education, the intermediate cycle between primary school and upper secondary school.
The institution's primary mission is to welcome students from its designated catchment area in order to provide them with a general education covering the various subjects of the common core of knowledge, skills, and culture. It also provides comprehensive educational support, including monitoring of schooling, school life, and various extracurricular activities and pedagogical projects aimed at fostering students' development and success. As such, it occupies a structuring place in the local educational landscape, working in conjunction with families, local authorities, and other stakeholders in the education system.
The website college-grenay.fr is the official website of the institution, presenting information about its organization, school life, news, and various resources intended for students, families, and the educational community.
