Ingress Filter

The ingress filter discards any incomming request that is not authorized before any other actions are taken.

Default behaviour

  • any email that is not on the allowlist is dropped unles the list check is disabled by an overwrite
  • if an ingress allowlist is configured any request not originating from a user on the list is dropped
  • List-manager request specific dropping rules only run if the list has the feature enabled and the target is about to trigger an action.
