Published record
v=DMARC1; p=quarantineWhat 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.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • At least one valid DKIM key published.
- • 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 Pontchâteau
The town hall of Pontchâteau is the municipal institution responsible for administering the commune of Pontchâteau, located in the Loire-Atlantique department, in the Pays de la Loire region. As a local authority, it constitutes the local level of French administrative organization and represents the interests of residents before other levels of government, while managing municipal affairs within the scope of competences assigned to it by law.
Pontchâteau is situated in a territory marked by the proximity of the Brière marshland and by a long history linked to the historic region of Brittany. The commune, whose heritage includes a calvary built in the nineteenth century that constitutes a recognized pilgrimage site, developed over time around agricultural and craft activities before undergoing economic and demographic diversification. It belongs to an intercommunal grouping within the Saint-Nazaire basin and benefits from a geographical position between the Loire estuary and the inland areas of Brittany.
The town hall carries out the missions traditionally entrusted to French communes: civil registry, management of public facilities, urban planning, social action, maintenance of communal roads, management of primary and nursery schools, as well as support for local associative, cultural and sporting activities. It also organizes elections and implements decisions made by the municipal council, the deliberative body chaired by the mayor. Its action is carried out in cooperation with the intercommunal body to which the commune is attached, particularly for shared competences such as economic development, housing or the environment. The local authority thus contributes to the development of the communal territory and to the quality of services provided to the population.
The website pontchateau.fr is the official website of the commune, presenting municipal information, administrative procedures and local news.
