v=DMARC1; p=quarantine; rua=mailto:informatique@vert-saint-denis.fr; ruf=mailto:informatique@vert-saint-denis.fr; sp=quarantineWhat this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • 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 Vert-Saint-Denis
Vert-Saint-Denis is a French municipality located in the Seine-et-Marne department, in the Île-de-France region. It belongs to the Melun district and is part of the Melun living area, close to the prefecture town of Melun. The municipality is a member of the Communauté d'agglomération Melun Val de Seine, an intercommunal structure to which it has transferred part of its powers, particularly in the areas of territorial planning, economic development, and the management of certain shared facilities.
The municipal territory combines residential areas, economic activity zones, and agricultural or natural spaces, typical of peri-urban municipalities in the outer Paris region. Like many localities in this part of Seine-et-Marne, Vert-Saint-Denis has evolved over the decades due to its proximity to transport routes connecting the Melun agglomeration to the rest of Île-de-France, which has supported residential development and the establishment of various activities within its boundaries.
As a basic-level local authority, the municipality carries out the missions traditionally assigned to French municipalities: general administration, civil registry, management of nursery and primary schools falling under its responsibility, maintenance of municipal roads, management of local sports, cultural, and community facilities, and the organization of proximity services for residents. The municipal council and the mayor exercise the executive and deliberative powers proper to the municipal level, within the framework set by the General Code of Territorial Authorities, in coordination with the relevant intercommunal and departmental bodies.
The website vert-saint-denis.fr is the municipality's official website, providing practical information on municipal life, administrative procedures, local news, and services offered to residents.
