Published record
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.
- • 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 Collège Rouget de Lisle
Collège Rouget de Lisle is a public secondary school located in Schiltigheim, a municipality in the Bas-Rhin department, part of the greater Strasbourg metropolitan area. It enrolls students from the first through the fourth year of lower secondary education, in line with the structure of the French education system. Its name honors Claude Joseph Rouget de Lisle, author of the French national anthem, a reference commonly chosen by schools throughout France.
Situated within the urban fabric of Schiltigheim, the school is part of the network of public institutions under the Strasbourg education authority (académie de Strasbourg). It serves a catchment area defined by school zoning regulations, welcoming students coming from surrounding elementary schools. Like other public French lower secondary schools, its operation is overseen by the Ministry of National Education for pedagogical matters, while the Bas-Rhin departmental council is responsible for facilities, building maintenance, and school catering.
The institution carries out the usual functions of a lower secondary school: delivering core curriculum instruction according to national programs, supporting students' guidance toward general, technological, or vocational pathways after their final year, and organizing school life through various governing bodies such as the administrative board or class councils. It may also offer specific programs, elective subjects, or educational projects reflecting its own institutional project, in line with regional and national educational guidelines.
The website collegerdl67.fr is the official website of Collège Rouget de Lisle in Schiltigheim, where information is published regarding the school's daily life, organization, pedagogical and administrative news, as well as practical procedures useful to families and students.
