Published record
v=DMARC1; p=quarantine; ruf=mailto:administrateur@sassenage.fr;What this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • No rua address: aggregate reports are not collected, which makes steering the hardening impossible.
- • At least one valid DKIM key published.
- • 1024-bit DKIM RSA key: still tolerated but below the state of the art — rotate to 2048 bits. (mail : 1024 bits)
- • 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 Sassenage
The Mairie de Sassenage refers to the municipal administration of the commune of Sassenage, located in the Isère department, in the Auvergne-Rhône-Alpes region of France. Situated at the edge of the Grenoble metropolitan area, at the foot of the Vercors massif, the commune's geography is marked by karstic reliefs and watercourses, including the Furon, which runs through its territory. This location makes it a natural gateway to the Vercors plateau while linking it to the broader living and employment area of Grenoble.
The history of Sassenage is long-standing and is notably connected to the lordship of the same name, whose castle, still standing today, bears witness to the site's medieval and early modern past. The commune is also known for a set of natural caves shaped by underground water, which have contributed to its local and regional reputation over the centuries. This heritage identity, blending nature and history, continues to largely shape the image of the municipal territory.
As a local government body, the Mairie de Sassenage exercises the powers typically assigned to French communes: management of local public services, urban planning, social action, education at the level of nursery and primary schools, maintenance of municipal roads, management of sports and cultural facilities, and organization of local civic and associative life. It also takes part in intercommunal cooperation within the Grenoble metropolitan area, through which certain responsibilities are shared with or transferred to a higher administrative level. The municipal council, chaired by the mayor, is the deliberative body responsible for setting local policy directions and voting on the municipal budget.
The website sassenage.fr is the official website of the commune of Sassenage, providing administrative and practical information as well as online services for residents and users.
