- • The subdomain policy (sp) is weaker than the main policy.
- • 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.

About Courrières
The Mairie de Courrières is the municipal administration of the commune of Courrières, located in the Pas-de-Calais department, in the Hauts-de-France region of France. It serves as the executive and administrative body responsible for managing local affairs on behalf of residents and the municipal territory. Situated in the heart of the former mining basin, the commune is set within an environment shaped by a rich industrial and social history.
Courrières is particularly known for the mining disaster that occurred in March 1906, one of the most severe accidents in the history of coal mining in Europe, an event that left a lasting mark on local and national collective memory. The commune forms an integral part of the Nord-Pas-de-Calais mining basin, several elements of which have been recognized as world heritage. This mining history has shaped the town's urban layout, social fabric, and identity, with its development long centered on extraction activity before a gradual shift toward other economic sectors.
The Mairie de Courrières exercises the usual responsibilities of a French municipal authority: civil registry services, urban planning, management of public facilities, social action, support for community and cultural life, as well as oversight of schools and local infrastructure. It also participates in intercommunal cooperation bodies to which the commune belongs, contributing to territorial planning and local development on a broader scale. Its role continues the tradition of French local authorities, tasked with representing the interests of residents and implementing local public policies.
The website courrieres.fr is the official website of the commune, providing municipal information, administrative procedures, and news related to local life.
