Published record
v=DMARC1; p=quarantine;What this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • No rua address: aggregate reports are not collected, which makes steering the hardening impossible.
- • 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 Persan
The Mairie de Persan is the municipal institution responsible for administering the commune of Persan, located in the Val-d'Oise department, in the Île-de-France region of France. Situated in the Oise valley, near Beaumont-sur-Oise, the commune lies northwest of Paris, in an area shaped by the presence of the river and rail infrastructure that historically encouraged its growth. The town hall serves as the seat of local executive authority and the main point of contact between residents and municipal services.
Persan developed from an old settlement core before experiencing, from the 19th century onward, growth linked to the establishment of industrial activities, particularly in the textile and metalworking sectors, favored by the proximity of the railway and the river. This industrial history shaped the urban and social fabric of the commune, which today is part of an intercommunal grouping in Val-d'Oise bringing together several neighboring municipalities that share common territorial planning and development concerns.
As a municipal administration, the Mairie de Persan carries out the responsibilities assigned to French local authorities at its level: civil registry management, urban planning and land use, maintenance of roads and public facilities, social services, management of municipal schools, support for community and cultural life, as well as the organization of local services for residents. It also represents the commune before departmental, regional, and intercommunal institutions and implements the decisions of the municipal council within its areas of competence.
The website ville-persan.fr is the official site of the commune, presenting institutional and practical information as well as online services intended for residents and users.
