- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • The subdomain policy (sp) is weaker than the main policy.
- • 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.
- • External report recipient not authorised (RFC 7489 §7.1): the _report._dmarc authorisation record is absent from the recipient domain — compliant reporters will ignore this rua/ruf address. (ca-pso.fr)

About Longuenesse
The Mairie de Longuenesse refers to the administrative institution of the commune of Longuenesse, a French local authority located in the Pas-de-Calais department, in the Hauts-de-France region. The commune lies in the immediate vicinity of Saint-Omer, within the same administrative district, in a territory characterised by wetlands and agricultural land typical of the Audomarois area. It forms part of the Communauté d'agglomération du Pays de Saint-Omer, with which it shares certain intercommunal responsibilities while retaining its own municipal prerogatives.
As the executive body of the commune, the town hall carries out the functions traditionally assigned to French local authorities: civil registry management, organisation of elections, issuance of administrative documents, urban planning and land use, maintenance of local roads, management of public facilities, and support for cultural, sporting and social activities for residents. The mayor, assisted by an elected municipal council, sets local policy directions and represents the commune before other administrative levels, including the intercommunal body, the department and the State.
Longuenesse has developed over time in close connection with the Saint-Omer urban area, of which it is one of the closest surrounding communes. Its territory includes structural facilities, residential areas and activity zones reflecting gradual growth linked to its geographical position. The commune is part of the planning dynamics specific to the Audomarois living area, coordinating with neighbouring authorities and intercommunal bodies while maintaining a distinct municipal identity within this territory.
The website ville-longuenesse.fr is the official institutional site of the commune, providing information on municipal life, administrative services, procedures for residents and local news.
