## Source (`kind` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../schema/kind.schema.json
# Sits in the MX or mailbox-API path and carries a delivery mode, per-disposition actions and a quarantine retention that firewall, waf and notification-service cannot express. deploymentMode and the disposition actions have no default so a rule can flag a gateway that inspects mail but never says what it does with a bad verdict.
