DAV was internal-only (the node's :443 is Traefik's). New mail-dav
Ingress routes /.well-known/caldav, /.well-known/carddav and /dav on
mail.dezky.eu through to Stalwart — with the HTTPS-redirect middleware
(safe for DAV's GET/PROPFIND; kept OFF the autodiscover Ingress whose
POSTs don't survive redirects). The _caldavs/_carddavs SRV records are
now legitimate, so the Domains page surfaces them, and the Apple
.mobileconfig gains CalDAV + CardDAV payloads: one install sets up Mail,
Calendar and Contacts on Mac/iPhone. Stalwart's STALWART_PUBLIC_URL is
set to https://mail.dezky.eu on the host (discovery documents).
The deploy failed creating the selectorless stalwart-http Service's
Endpoints: since the CVE-2021-25740 hardening the namespaced 'admin' role
no longer grants write on legacy Endpoints. Explicit endpoints +
endpointslices rules on the ci-deployer role (already applied live);
manifest comment touch retriggers the infra apply.
Outlook autodiscovers via POST https://autodiscover.<domain>/autodiscover/
autodiscover.xml and Thunderbird via autoconfig.<domain>/mail/
config-v1.1.xml — Stalwart serves both (verified, answers carry
mail.dezky.eu:993/465) but its HTTP listener wasn't reachable from
outside (the node's :443 is Traefik's). New exact-path-only Ingress
routes JUST those discovery endpoints to host-Stalwart via a selectorless
Service + Endpoints on the cni0 gateway; the admin/management surface
stays internal, and there's no HTTPS-redirect middleware because
Thunderbird probes plain HTTP and Outlook POSTs.
Domains page now also lists the autoconfig/autodiscover CNAMEs under the
autodiscovery slot (CNAME verified against the mail host; a bare A record
warns instead of failing). Customer-domain autodiscovery (per-domain
certs + automated Ingress) is a follow-up.
