v=DMARC1; p=reject; rua=mailto:a@dmarc.facebookmail.com; ruf=mailto:fb-dmarc@datafeeds.phishlabs.com; pct=100What this means
- • Policy p=reject: maximum protection against spoofing.
- • SPF with no final “all” mechanism: neutral default behaviour.
- • A DKIM key has an empty p= field (revoked key).
- • No DKIM key found on the common selectors (the domain may use non-standard selectors).
- • DKIM key in test mode (t=y): remove the flag once the signature is validated in production. (default)
- • MTA-STS policy in testing mode: no effective blocking — aim for mode: enforce.
- • TLS-RPT published: sending servers report the TLS failures they encounter when connecting to the domain’s MX.
- • 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. (dmarc.facebookmail.com)

About Saint-François
The Mairie de Saint-François refers to the municipal administration of the commune of Saint-François, located in Guadeloupe, on the eastern coast of Grande-Terre, in the French Antilles. This local government body constitutes the local tier of the French administrative organization and represents the executive authority responsible for managing municipal affairs across the relevant territory, including the town center and surrounding districts.
Historically, Saint-François developed from agricultural activities, particularly related to sugarcane, before undergoing economic diversification driven by seaside tourism and maritime activities. The commune features a coastline marked by beaches, a marina, and a fishing port, elements that have helped shape its identity and appeal within the Guadeloupean archipelago. This evolution has gradually led the municipality to adapt its infrastructure and services to meet the needs of both a resident population and seasonal tourist visits.
The town hall exercises the powers typically assigned to French communes: civil registry, management of primary and nursery schools, urban planning and issuance of building permits, maintenance of municipal roads, local social action, organization of cultural events, and support for local associations. It also administers public property and takes part in defining territorial development orientations, in coordination with higher-level authorities, notably the Guadeloupe Region and the Department. The municipal council, made up of local elected officials, together with the mayor, sets budgetary priorities and structural projects for the commune, within the framework of the legal powers granted to French municipalities.
The website facebook.com is a social networking platform on which the Mairie de Saint-François publishes information, announcements, and news related to municipal life.
