- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • The subdomain policy (sp) is weaker than the main policy.
- • 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. (selector1 : 1024 bits)
- • No MTA-STS (_mta-sts): inbound SMTP connections remain exposed to TLS downgrade. Recommended alongside DMARC.

About Lycée polyvalent privé et campus Saint-Joseph
The Lycée polyvalent privé et campus Saint-Joseph is a private educational institution located in Saint-Martin-Boulogne, in the Pas-de-Calais department, in the Hauts-de-France region of France. It follows the tradition of Catholic educational establishments, typically affiliated with a congregational or diocesan network, and offers an educational pathway structured across several levels of schooling, from secondary education through to post-baccalaureate programs, under the designation of a campus. This campus-based organization reflects an intention to bring together various tracks and levels within a single site, thereby fostering pedagogical continuity for students throughout their studies.
The institution positions itself as a private, state-contracted education provider in the Boulogne area, serving families from Saint-Martin-Boulogne and surrounding municipalities, including the greater Boulogne-sur-Mer area. Its scope of activity covers general, technological and, depending on the tracks offered, vocational education, alongside an educational approach rooted in a Catholic-oriented project. The establishment serves secondary-level students and, for certain programs, short-cycle higher education students as well.
Lycée Saint-Joseph is part of the network of private educational institutions in Pas-de-Calais, alongside similar establishments, and contributes to the local educational offering alongside public schools. Its approach combines academic instruction with values-based formation, a characteristic feature of Catholic educational institutions. Its location in Saint-Martin-Boulogne, a municipality bordering Boulogne-sur-Mer, places the institution in a coastal geographic context near the English Channel.
The website st-jo.com is the institution's official website, presenting its educational programs, news updates, enrollment procedures, and various practical information intended for families and students.
