Published record
v=DMARC1; p=none;What 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 Montmagny
The Mairie de Montmagny is the administrative institution representing the town of Montmagny, a French municipality located in the Val-d'Oise department, in the Île-de-France region. It constitutes the local executive body responsible for managing municipal affairs and implementing decisions made by the municipal council, under the authority of the mayor elected by that council. The town is part of the urban fabric of the northern suburbs of Paris, close to other municipalities in the department such as Deuil-la-Barre, Groslay and Saint-Gratien.
Like many municipalities in the Paris region, Montmagny has undergone a gradual evolution over time, moving from a more rural setting to increasing urbanization linked to the expansion of the Paris metropolitan area. The town hall ensures the administrative continuity of the municipality through the various stages of its development, adapting to the demographic and territorial changes characteristic of this part of Île-de-France.
The Mairie de Montmagny exercises the standard responsibilities assigned to French municipalities: civil registry, urban planning, management of municipal facilities, social action, education and childhood services, as well as the maintenance of local roads and public spaces. It works with intercommunal and departmental institutions in Val-d'Oise to implement certain public policies, particularly regarding land use planning and services for residents. It thus represents the local level of public administration for the town's residents, serving as an interface between inhabitants and the various levels of territorial administration.
The website villedemontmagny.fr is the official website of the town, providing municipal information as well as online services and administrative procedures for residents.
