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.
- • 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 Trignac
Trignac is a French commune located in the Loire-Atlantique department, in the Pays de la Loire region. It lies within the Saint-Nazaire urban area, close to the Loire estuary, and is part of the Communauté d'agglomération de la région nazairienne et de l'estuaire (CARENE). Its territory, shaped by an industrial history linked in particular to metallurgy and the region's port activities, today combines residential areas, economic zones and natural spaces near the coastline and surrounding marshlands.
As a local authority, the commune of Trignac is administered by a municipal council and a mayor, in accordance with the communal organization set out under French law. Its scope of action covers the usual competencies of French communes: management of local public facilities, urban planning, local social services, maintenance of communal roads, and support for educational, cultural and sporting institutions within its territory. It also carries out certain missions in coordination with the intercommunal body it belongs to, particularly regarding economic development, territorial planning, and shared services at the scale of the Saint-Nazaire agglomeration.
Trignac's geographical position, at the crossroads of the port, industrial and residential dynamics of the Loire estuary, gives it a specific role within the Saint-Nazaire living area. The commune takes part in local public policies coordinated with the other member municipalities of CARENE, while retaining its own municipal governance for matters strictly within its communal boundaries. Its history, marked by the development of steel-related industries during the 19th and 20th centuries, continues to shape the identity and spatial organization of the present-day territory.
The website mairie-trignac.fr is the official website of the Trignac town hall, presenting administrative and practical information about the commune as well as services and procedures available to residents.
