What this means
- • No DMARC record published (_dmarc). Receivers have no policy to apply.
- • 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 Institut Sandar La Salle
Institut Sandar La Salle is a secondary education establishment located in Limonest, a commune in the Rhône department, in the Auvergne-Rhône-Alpes region of France. Its name refers to the Lasallian educational tradition, a pedagogical movement historically associated with Catholic teaching institutions in France, several of which bear the name "La Salle" in reference to Jean-Baptiste de La Salle, founder of this pedagogy. Its location in Limonest, a peri-urban commune within the Lyon metropolitan area, places the institution in an environment that is both residential and close to the infrastructure of the Lyon metropolis.
The institution offers a schooling path corresponding to lower and/or upper secondary levels, welcoming students within an educational project structured around pedagogical and human values specific to the network it belongs to. Its scope of activity covers general education, delivered according to the usual cycles of the French school system, with supervision provided by a teaching and educational staff. The institution is thus part of the fabric of private schools under contract or affiliated with faith-based networks, contributing to the local educational offer alongside other public and private school structures present in the Lyon basin.
In terms of its positioning, Institut Sandar La Salle occupies a place within the educational network of the Limonest area and its surroundings, contributing to the schooling of young people in the territory. Its local roots are accompanied by integration into networks of institutions claiming the Lasallian pedagogy, a network present in several French regions and internationally. The institution maintains relations with local authorities and competent academic bodies, within the regulatory framework applicable to school institutions in French territory.
The website sandar.org is the official website of the institution, presenting information about its organization, its educational project, and its operating arrangements for families and the interested public.
