Published record
v=DMARC1; p=reject; pct=100; adkim=s; aspf=s;What this means
- • Policy p=reject: maximum protection against spoofing.
- • 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 Fontainebleau
The Fontainebleau town hall (mairie) is the municipal administration of the commune of Fontainebleau, a French local authority located in the department of Seine-et-Marne, in the Île-de-France region. It serves as the executive body responsible for managing local affairs, under the authority of the mayor and the municipal council elected by the town's residents. Fontainebleau owes its historical prominence to its château, a former royal and imperial residence, which has shaped the urban development and identity of the town over the centuries.
The commune is located southeast of the Paris metropolitan area, on the edge of the forest that also bears the name Fontainebleau, a protected natural area that plays a significant role in the town's immediate environment. This location gives the commune a character that is at once heritage-related, touristic and residential, while integrating it into a broader living area structured around several neighboring communes with which it maintains administrative and functional ties.
The Fontainebleau town hall exercises the powers typically assigned to French communes: civil registry, urban planning, management of public facilities, social action, culture, primary-level education, maintenance of local roads, and organization of local civic life. It also participates, in coordination with intercommunal bodies and other local authorities, in territorial planning, the preservation of historical and natural heritage, and the development of services for residents, businesses and visitors. Its action takes place within the legal and regulatory framework applicable to French local authorities, in coordination with state services present within the department.
The website fontainebleau.fr is the official institutional site of the commune, presenting information about the local authority and online services intended for residents and users.
