v=DMARC1; p=none;Was das bedeutet
- • Politique p=none : surveillance seule, aucun message non authentifié n'est bloqué.
- • Aucune adresse rua : les rapports agrégés ne sont pas collectés, impossible de piloter le durcissement.
- • Au moins une clé DKIM valide publiée.
- • Clé DKIM RSA de 1024 bits : encore tolérée mais sous l’état de l’art — faire tourner vers 2048 bits. (selector1 : 1024 bits)
- • Pas de MTA-STS (_mta-sts) : les connexions SMTP entrantes restent exposées au downgrade TLS. Recommandé en complément de DMARC.

Über Communauté d'agglomération - Grand Sénonais
The Communauté d'agglomération du Grand Sénonais is a French local authority classified as a public establishment for inter-communal cooperation (EPCI). It brings together several municipalities located in the Yonne department, in the Bourgogne-Franche-Comté region, centered around the town of Sens. This inter-municipal structure emerged from the gradual development of cooperation among neighboring communes, part of a broader movement toward streamlining territorial organization in France, encouraged by successive laws on inter-municipal cooperation.
The territory of the Grand Sénonais spans an area combining urban, peri-urban and rural zones, anchored in the northern part of the Yonne department, close to the routes linking Paris to Burgundy. The agglomeration exercises powers assigned to it by law or transferred by its member municipalities, particularly in the areas of spatial planning, economic development, housing management, urban policy, as well as local public services such as waste collection, water and sanitation, and local public transport. It also acts in the fields of culture, sport and social action, complementing municipal-level policies.
As an inter-municipal tier of government, the Grand Sénonais plays a coordinating role among its member communes, pooling certain resources and carrying forward structural projects at the scale of the Sens living area. It serves as an institutional partner for public and private stakeholders in the implementation of development projects, economic initiatives and collective facilities, thereby contributing to the organization and territorial coherence of this part of the Yonne department. The website grand-senonais.fr is the official institutional site of this agglomeration community, presenting its responsibilities, organization and practical information intended for residents and local stakeholders.
