Published record
v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.comWhat this means
- • Policy p=none: monitoring only, no unauthenticated message is blocked.
- • 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. (selector1 : 1024 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 Saint-Ismier
Saint-Ismier is a French municipality located in the department of Isère, in the Auvergne-Rhône-Alpes region. Situated in the Grésivaudan valley, near Grenoble, it benefits from a geographical position framed by the Chartreuse massif and the Belledonne massif, which enclose the valley. This location makes it a peri-urban municipality appreciated for its living environment, combining proximity to urban services in Grenoble with a preserved natural setting.
Like any French municipality, Saint-Ismier constitutes a basic territorial authority governed by an elected municipal council and a mayor responsible for its administration. The municipality exercises the traditional powers devolved to French local authorities: civil registry management, urban planning and land development, maintenance of municipal roads, management of local public facilities such as primary and nursery schools, as well as the organization of cultural, sporting and social activities for residents. It is also part of an intercommunal structure in the Grésivaudan area, with which it shares certain responsibilities in economic development, transport, and environmental matters.
The municipal territory is characterized by a combination of residential areas, natural zones, and some local economic activities, reflecting a medium-sized municipality within the Grenoble metropolitan basin. Its geographical position, between mountains and the urban agglomeration, contributes to its residential appeal while functionally linking it to the Grenoble living and employment area. The municipality thus participates in the territorial dynamics of the Grésivaudan valley, both demographically and in terms of planning and local public services for its population.
The website saint-ismier.fr is the official institutional portal of the municipality, presenting administrative, practical and municipal information as well as online services intended for residents and users.
