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 Chassieu
The town hall of Chassieu is the municipal administration of the commune of Chassieu, located in the Rhône department, within the Lyon metropolitan area, in the Auvergne-Rhône-Alpes region of France. It constitutes the local executive body responsible for implementing the decisions of the municipal council and managing communal affairs, under the authority of the mayor elected by the council members. As with any French local government at the municipal level, it exercises its powers within the framework of the general code of territorial authorities and works in coordination with the intercommunal bodies of the Lyon metropolitan area.
Chassieu is located to the east of the Lyon urban area, near Lyon-Saint-Exupéry Airport, and benefits from a geographic position that has made it a recognized hub for economic and logistics activities in the region. Over the decades, the commune has undergone a gradual transformation, evolving from a rural character to an identity combining residential areas, business zones, and public facilities, while retaining certain heritage elements that reflect its long history.
The town hall carries out a range of local services for residents and economic actors: civil registry, urban planning, management of municipal facilities, social, educational and cultural actions, as well as maintenance of infrastructure and public spaces. It also plays a role in supporting community and civic life within the commune, coordinating with the services of the Lyon metropolitan authority on shared responsibilities such as roads, transport, and local economic development. It thus serves as the primary institutional point of contact for residents and businesses established within the communal territory.
The website chassieu.fr is the official institutional site of the commune, providing information on municipal life, administrative procedures, and services available to residents.
