Published record
v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.comWhat this means
- • Policy p=none: monitoring only, no unauthenticated message is blocked.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • 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 Montoir-de-Bretagne
Montoir-de-Bretagne is a French commune located in the Loire-Atlantique department, in the Pays de la Loire region. Situated on the northern bank of the Loire estuary, immediately adjacent to Saint-Nazaire, it occupies a strategic position in western France, between port and industrial zones and natural areas characteristic of the Atlantic coastline. The commune is part of the Communauté d'agglomération de la région nazairienne et de l'estuaire (CARENE), with which it shares several intercommunal competencies in spatial planning and economic development.
The history of Montoir-de-Bretagne is closely linked to that of the Loire estuary, whose port and industrial exploitation shaped the territory's development throughout the twentieth century. The commune progressively hosted facilities related to the activities of the Nantes-Saint-Nazaire autonomous port, which contributed to structuring its local economic fabric around industrial, logistics, and energy sectors. This evolution forms part of a broader trajectory of development in the Nazairian basin, marked by the growth of port and manufacturing activities.
As a territorial authority, the commune carries out the traditional missions assigned to French municipalities: management of local public services, urban planning, maintenance of municipal facilities, civil registry, and civic life coordination. It also plays a role in preserving and enhancing its environment, characterized by the coexistence of protected natural areas and economic activity zones. The municipal council, elected by residents, governs the commune and represents it before intercommunal, departmental, and regional bodies.
The website montoirdebretagne.fr is the official site of the commune, where information related to municipal life, administrative procedures, and services offered to residents is published.
