- • 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 Grenay
Grenay is a French commune located in the Pas-de-Calais department, in the Hauts-de-France region. It lies within the territory of the former mining basin, close to the towns of Lens and Liévin, in an area marked by a long industrial tradition and by the history of coal mining, which shaped the local urban landscape. The commune administratively belongs to the Lens district and is part of the intercommunal framework specific to this part of the department.
Like any local authority of this kind, Grenay has a municipal council and a communal administration responsible for managing local affairs, maintaining public facilities, organising local services, and implementing municipal policies in areas such as urban planning, social action, community life, education, and territorial development. The commune also takes part in the intercommunal cooperation bodies that structure local public action within the mining basin, working alongside neighbouring authorities and the departmental and regional levels.
The communal territory, shaped by its mining past, has undergone urban and social changes typical of the former working-class settlements of the region, while gradually adapting to the economic and demographic transformations that have affected the entire mining basin since the end of coal-mining activity. The municipality thus continues its work of local management and development, seeking to maintain services suited to the needs of the resident population and to promote local heritage, particularly that inherited from the mining history, within the scope of competences assigned to the municipal level in the French territorial organisation.
The website grenay.fr is the official website of the commune of Grenay, presenting information about municipal life, communal services, administrative procedures, and local news.
