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 Mainvilliers
The town hall of Mainvilliers is the municipal administration of the French commune of Mainvilliers, located in the Eure-et-Loir department, in the Centre-Val de Loire region. It constitutes the executive and administrative body responsible for managing local affairs, under the authority of the mayor and municipal council elected by residents. Like any commune-level local authority in France, it implements the decisions made by local elected officials and ensures the operation of proximity public services.
Mainvilliers is a commune bordering the city of Chartres, forming one of its urban extensions to the west. It belongs to the Chartres metropolitan area and falls within the perimeter of the intercommunal body that groups together the communes of the Chartres living area. This geographic situation makes it a predominantly residential commune, while retaining its own facilities and activities that structure local life.
The responsibilities of the town hall cover the usual competencies assigned to French communes: civil registry, urban planning, management of municipal facilities, maintenance of communal roads, local social action, as well as support for school, extracurricular, cultural, and sports activities intended for residents. It also organizes electoral processes and issues various administrative acts and documents. The town hall serves as a primary point of contact between residents and other levels of public administration, whether the intercommunal body, the department, or the state, and participates in territorial cooperation bodies specific to the Chartres area.
The website ville-mainvilliers.fr is the commune's institutional site, presenting information related to municipal organization, administrative procedures, services offered to residents, as well as local life and news from the local authority.
