- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • 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 Lannion
The Mairie de Lannion is the administrative institution governing the commune of Lannion, the seat of an arrondissement in the Côtes-d'Armor department, in the Brittany region of France. Located in the Trégor area, on the banks of the Léguer river and near the English Channel coast, the commune occupies a strategic geographic position between the coastline and the inland territory, which has favored its development over the centuries as a center of trade and services for surrounding communities.
The history of Lannion dates back to medieval times, as reflected in its Templar church and its old quarter of half-timbered houses, elements that today shape its architectural heritage. During the twentieth century, the town underwent notable economic transformation linked to the establishment of research and technological innovation activities, which helped diversify an economy traditionally oriented toward agriculture and local trade. This evolution made Lannion a recognized hub within its local area, combining historical heritage with contemporary economic dynamism.
As a local government body, the mairie carries out the responsibilities assigned to French communes: civil registration, urban planning, management of public facilities, social welfare services, oversight of primary schools, as well as maintenance of roads and municipal public spaces. It is also part of the intercommunal structure to which Lannion belongs, which pools certain responsibilities with neighboring communes in the Trégor area, particularly regarding economic development, territorial planning, and management of shared services. The mairie thus serves as the local link between residents and public policy, while participating in territorial cooperation bodies at the level of the surrounding area.
The site lannion.bzh is the official institutional website of the commune, providing administrative information, municipal news, and online procedures for residents and users.
