Published record
v=DMARC1; p=noneWhat 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.
- • 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 Guilherand-Granges
The Mairie de Guilherand-Granges refers to the municipal administration of the commune of Guilherand-Granges, located in the Ardèche department, in the Auvergne-Rhône-Alpes region of France. Situated on the right bank of the Rhône river, facing the city of Valence to which it is connected by several bridges, the commune is part of an urban living area structured around the Valence agglomeration. It belongs to the Valence Romans Agglo intercommunal body, which brings together several communes from the Drôme and Ardèche territories around shared responsibilities in planning and local public services.
Guilherand-Granges resulted from the administrative merger of two distinct localities, Guilherand and Granges-lès-Valence, whose union marked the commune's history during the twentieth century before it took its current name. This merger history is still reflected today in the organization of the municipal territory, which combines residential neighborhoods, economic activity zones, and areas located along the riverbank. The commune's development has been accompanied by demographic growth and a gradual diversification of its urban fabric, linked to its immediate proximity to Valence.
The mairie carries out the traditional responsibilities assigned to communal authorities in France: managing civil registry records, issuing administrative documents, organizing elections, handling urban planning and building permits, managing school, after-school, sports, and cultural facilities, as well as maintaining roads and public spaces. It is administered by an elected municipal council, headed by a mayor, and relies on administrative services organized into departments and thematic units to implement local public policies, in coordination with responsibilities exercised at the intercommunal level.
