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. (selector1 : 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 Cesson
The town hall of Cesson is the administrative institution representing the commune of Cesson, a French territorial authority located in the Seine-et-Marne department, in the Île-de-France region. It constitutes the local executive body responsible for implementing municipal decisions and managing communal affairs, under the authority of the mayor and the municipal council elected by residents. The commune is part of the Melun urban area, close to the city of Melun, the department's prefecture, and participates in the territorial dynamics of this southern sector of Île-de-France, characterized by a mix of residential spaces, economic activity, and natural areas.
The history of Cesson is tied to that of the Seine-et-Marne territory, whose modern administrative organization developed through successive territorial reforms since the French Revolution. Like many communes in the region, Cesson has undergone a gradual evolution of its urban fabric, moving from an initially rural character to a more diversified configuration incorporating residential, commercial, and activity zones, in connection with the development of the Melun urban area and the transport infrastructure serving the sector.
The town hall carries out the full range of tasks assigned to French communal authorities: civil registry management, urban planning and land use, maintenance of roads and public spaces, local social services, management of school, sports, and cultural facilities, as well as the organization of municipal services for the benefit of residents. It also represents the commune in its relations with other administrative levels, notably the department and the intercommunal body to which it belongs, and takes part in territorial consultation bodies concerning local planning and development.
The website ville-cesson.fr is the commune's institutional website, presenting information on municipal life, administrative procedures, local public services, and news from the local authority.
