How to fix it

Thomas, your AI-powered virtual CISO, finds every sender, writes the exact DNS, and walks your domain safely from p=none to p=reject.

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 Lycée Jean Perrin

Lycée Jean Perrin is a public secondary school located in Lambersart, a town in the Nord department, within the greater Lille metropolitan area of France. It bears the name of the French physicist Jean Perrin, known for his work on the structure of matter and recipient of the Nobel Prize in Physics. Like most French public lycées, it operates under the French Ministry of National Education and is part of the network of institutions within the Lille education authority (académie de Lille). The school's main mission is to provide secondary-level education, preparing students for the various tracks of the French baccalauréat examination. It offers a structured pedagogical framework centered on general education and, depending on its specific organization, may also host technological programs or post-secondary complementary courses. The school primarily serves young people from the local area, drawing mainly from Lambersart and neighboring communities within the Lille metropolitan region. As a public institution, Lycée Jean Perrin is part of the territorial network of educational structures in the Nord department, contributing to the secondary education offering in this part of the Hauts-de-France region. Its geographic position, close to Lille, allows it to be part of a dense educational environment alongside other public and private schools serving the metropolitan area. It operates according to the principles and regulatory framework specific to the French school system, under the authority of the relevant academic services. The website lyceejeanperrin.fr is the school's official website, presenting information about its organization, educational tracks, and school life.
