Then that should suffice for Alex's purposes. He should not have to "discover" that the gateway is active. If he gets a message on the archive service interface, he sends it out. If it doesn't appear, it wasn't meant to be.

Yes, this also allows George to collect metrics about messages without having the underlying messages archived. Or it also allows the messages to be archived without being counted by the metrics. It's all up to how our users choose to configure things.

This is a more general question concerning just how the configuration service enforces site policies.

On an implementation level, it gets mapped so that, to each of the various message handling services, each list has its own full set of configuration parameters. In other words, a message handler does not care whether "switch x" is set because it is set specifically for the current list or because it is set for all of the lists within some collection of lists.
