- • 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.
- • No DKIM key found on the common selectors (the domain may use non-standard selectors).
- • 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 Arcachon
The town hall of Arcachon is the municipal institution of the commune of Arcachon, located in the Gironde department, in the Nouvelle-Aquitaine region, on the southern shore of the Arcachon Bay, along the Atlantic coast. Founded in the mid-19th century on land formerly belonging to La Teste-de-Buch, from which it separated in 1857, Arcachon originally developed around a thermal and seaside vocation, later becoming a recognized tourist destination throughout its history. The town grew around distinct historic districts, organized according to the original seasonal patterns of visitors, such as the Winter Town, Summer Town, Spring Town and Autumn Town, reflecting this particular heritage identity.
Situated in an area shaped by the proximity of the ocean, the Landes forest and the bay, the commune lies within a specific natural environment, combining maritime, oyster-farming and tourism activities. It belongs to an intercommunal grouping of several communes bordering the Arcachon Bay, with which it shares certain responsibilities related to territorial planning and local development.
The town hall carries out the traditional duties assigned to a French local authority: civil registry, management of municipal facilities, urban planning, social action, education, culture and environmental matters. It is also involved in organizing local life, managing public spaces, maintaining municipal infrastructure and supporting projects related to tourism and heritage, sectors that are particularly structuring for the local economy. The municipal administration is led by an elected mayor and municipal council, in accordance with the provisions of French local government law.
The website ville-arcachon.fr is the official site of the commune, providing practical information about municipal services, administrative procedures, local life and town news.
