A newly received InboundEmail will not be routed synchronously as part of ingress controller's receival. Instead, the routing will be done asynchronously, using a RoutingJob, to ensure maximum parallel capacity.

By default, all newly created InboundEmail records that have the status of pending, which is the default, will be scheduled for automatic, deferred routing.
