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.
- • 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 Blain
The Mairie de Blain is the administrative institution responsible for the governance and management of the commune of Blain, a French local authority located in the Loire-Atlantique department, in the Pays de la Loire region. As the local executive body, it represents the municipal authority in charge of implementing the decisions of the municipal council and ensuring the operation of public services intended for the commune's residents.
Located in the northwestern part of the Loire-Atlantique department, at a moderate distance from Nantes, Blain developed around a site marked by the presence of a medieval castle, a legacy of its past as a fortified stronghold, and by the passage of the Nantes-Brest canal, which for a long time shaped its economic activity and urban layout. This geographic position, at the crossroads of historic transport routes, has contributed to shaping the commune's identity over the centuries, combining rural heritage with the gradual development of its urban and economic fabric.
The scope of activity of the Mairie de Blain covers the full range of responsibilities traditionally assigned to French communes: civil registry management, issuance of administrative documents, urban planning and land management, maintenance of local roads, management of school and after-school facilities, social welfare action, and support for local cultural and associative life. It carries out its missions in coordination with the intercommunal bodies to which the commune belongs, as well as with departmental and regional authorities, within the general framework of French territorial organization. It thus serves as the main point of contact for residents regarding matters related to daily life and local administration.
The website ville-blain.fr is the official institutional site of the commune of Blain, presenting administrative procedures, municipal news, services offered to residents, and practical information about local life.
