+# TLS certificate for the Stalwart mail listeners (SMTP/IMAP/POP3 STARTTLS + implicit TLS)
+# and the management WebUI hostname.
+#
+# Issued by cert-manager via the letsencrypt-production ClusterIssuer (Cloudflare DNS-01).
+# The resulting Secret (mail-vhaudiquet-fr-tls) is consumed in two places:
+#   1. The Stalwart HelmRelease mailTls block -> mounted into the pod + pushed to
+#      Stalwart by the tls-sync sidecar (JMAP) so SMTP/IMAP/POP3 present this cert.
+#   2. The chart ingress (TLS termination is handled by Caddy in this cluster, so the
+#      ingress is TLS-less and only routes HTTP to the mgmt port).
