Published record
v=DMARC1; p=noneWhat this means
- • Policy p=none: monitoring only, no unauthenticated message is blocked.
- • 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 Dinan
The Mairie de Dinan is the municipal administration of the commune of Dinan, a French local authority located in the Côtes-d'Armor department, in the Brittany 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 commune's residents. This institution operates within the French administrative system, which grants communes specific responsibilities for local governance and services provided to residents.
Dinan is a historic town situated on the heights overlooking the Rance valley, known for its medieval heritage, its ramparts and its well-preserved old town centre. The commune developed over the centuries around a strategic site linked to river navigation and trade between inland areas and the Breton coast. It now holds a position as a local hub within the surrounding territory, while retaining a strong heritage identity that shapes its urban organisation and development.
The Mairie de Dinan carries out a range of tasks falling under municipal competences as defined by French law, including civil registry services, urban planning, management of public facilities, local social support, maintenance of communal roads, administration of primary and nursery schools, and support for local cultural and community activities. It also ensures the preservation and promotion of the town's historic heritage, a central element of its identity. The institution works alongside other administrative levels, particularly at the intercommunal and departmental scale, in the implementation of public policies suited to the territory. The website dinan.fr is the official institutional site of the commune of Dinan, providing administrative information, online procedures and news related to municipal life.
