- • Policy p=reject: maximum protection against spoofing.
- • 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 Billy-Montigny
Billy-Montigny is a French commune located in the Pas-de-Calais department, in the Hauts-de-France region. It lies within the former mining basin of Nord-Pas-de-Calais, an area historically shaped by coal extraction, which influenced its urban development, housing patterns and social fabric. The commune belongs to the arrondissement of Lens and maintains close ties with neighbouring municipalities within this shared living area, marked by a strong industrial identity inherited from the nineteenth and twentieth centuries.
As a territorial authority, Billy-Montigny is governed by a municipal council and a mayor, in accordance with the principles of French communal administration. It exercises the standard responsibilities assigned to municipalities, including civil registry management, urban planning, the operation of local public facilities, community-based social action and support for associative life. It also participates in intercommunal structures that allow for the pooling of certain services and the coordinated exercise of competences related to spatial planning, economic development and environmental matters.
The heritage of Billy-Montigny reflects its mining past, featuring workers' housing estates, collective facilities inherited from that era, and an industrial memory that is locally valued. The commune is now engaged in a process of renewal and evolution of its living environment while retaining the distinctive traits of its history.
