Published record
v=DMARC1;p=quarantineWhat this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • No rua address: aggregate reports are not collected, which makes steering the hardening impossible.
- • SPF ends with ~all (softfail): acceptable while observing, aim for -all in the end.
- • No DKIM key found on the common selectors (the domain may use non-standard selectors).
- • 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 Mont-Saint-Martin
Mont-Saint-Martin is a French municipality located in the Meurthe-et-Moselle department, in the Grand Est region. It lies at the northern edge of French territory, bordering Luxembourg and close to Belgium, giving it a distinctive cross-border position within the Longwy basin. The municipality is situated in a geographical area marked by the Chiers valley and by an urban fabric historically linked to the region's industrial activity.
The history of Mont-Saint-Martin is closely tied to the development of the Lorraine steel industry, which shaped its urbanization and social organization throughout the twentieth century. Like many municipalities in the Longwy basin, it experienced significant economic changes linked to the decline and subsequent conversion of the iron and steel industry, which influenced its urban and demographic development. The municipality is part of the Longwy urban community, an intercommunal structure that coordinates certain responsibilities across the cross-border living area.
As a territorial authority, the municipality of Mont-Saint-Martin carries out the traditional duties assigned to French municipalities: managing local public services, urban planning, social action, maintaining collective facilities, and supporting local community life. It also takes part in intercommunal and cross-border cooperation bodies related to its geographical location, particularly regarding economic relations and mobility with neighboring Luxembourg. Its position makes it a place of passage and residence for part of the population working across the border.
The website mairie-montsaintmartin.fr is the institutional website of the municipality, presenting administrative information, local news, and services intended for residents.
