Published record
v=DMARC1; p=none;What 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.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • At least one valid DKIM key published.
- • 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 Cosne-Cours-sur-Loire
Cosne-Cours-sur-Loire is a French municipality located in the Nièvre department, within the Bourgogne-Franche-Comté region. It resulted from the merger of several riverside entities along the Loire, which explains its compound name, and occupies a notable geographic position at the confluence of the river and the Nohain stream. This location has historically made it a point of transit and exchange, fostering the development of commercial and craft activities along the riverbanks.
The municipality exercises the usual responsibilities of a local authority of its kind: civil registry management, urban planning, maintenance of municipal roads, local social services, management of educational, sports and cultural facilities, as well as the organization of community life. It also serves as an administrative hub for its surrounding area, hosting public services intended for residents of the broader living area. Its role as a sub-prefecture gives it an administrative function extending beyond the municipal scope alone, in connection with state services present on the territory.
The municipal territory is set within a rural and riverside environment characteristic of the Loire Valley, with a built heritage reflecting several centuries of urban history, particularly around the old town center and the bridges spanning the waterways. The municipality takes part in intercommunal dynamics for the management of shared responsibilities, such as economic development, land use planning, or the management of certain local public services, in cooperation with neighboring municipalities. It is thus part of a broader territorial network while retaining its own administrative identity, represented by its municipal council and mayor, the decision-making and representative bodies of the local authority before its residents and institutional partners.
The website mairie-cosnesurloire.fr is the institutional website of the municipality, presenting general information about the local authority, its municipal services, administrative procedures and local life.
