Published record
v=DMARC1;p=quarantine;rua=mailto:admin@alpi40.fr;What this means
- • Policy p=quarantine: unaligned messages are moved to the spam folder.
- • 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.
- • 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. (alpi40.fr)

About Castelsarrasin
The Mairie de Castelsarrasin is the municipal institution that administers the commune of Castelsarrasin, a French local authority belonging to the Tarn-et-Garonne department, in the Occitanie region. It constitutes the local executive and administrative body responsible for implementing the decisions of the municipal council and managing the day-to-day affairs of the commune, in accordance with the general framework of French territorial organization.
Castelsarrasin holds the status of sub-prefecture within the Tarn-et-Garonne department, giving it an administrative role as a link between state services and surrounding communes. The town is situated in an area marked by the proximity of the Garonne canal and by a long history tied to the agricultural and commercial development of southwestern France. This geographic setting has shaped the urban and economic development of the commune over the centuries, combining rural, artisanal, and administrative activities.
The scope of the mairie's activity covers the full range of responsibilities assigned to French communes: civil registry, urban planning, management of public facilities, social services, education at the nursery and primary school level, maintenance of local roads, and the organization of cultural and community life. The institution also serves as an interface with residents for routine administrative procedures and takes part in the intercommunal bodies in which the commune participates. It thus represents the local level of public action, serving residents and local economic actors within the powers granted by law to territorial authorities.
The website ville-castelsarrasin.fr is the official website of the commune, providing institutional, practical, and cultural information as well as online services for residents and users.
