MinIO also sends with the notifications two headers: `minio-bucket` and `minio-event`. An exchange using the type "headers" can use this information to route the notifications to proper queues.

Note that, you can add as many AMQP server endpoint configurations as needed by providing an identifier (like "1" in the example above) for the AMQP instance and an object of per-server configuration parameters.

	if err = config.Validate(globalSite.Region, globalEventNotifier.targetList); err != nil {
		arnErr, ok := err.(*event.ErrARNNotFound)
		if ok {
			for i, queue := range config.QueueList {
				// Remove ARN not found queues, because we previously allowed
				// adding unexpected entries into the config.
				//
				// With newer config disallowing changing / turning off
				// notification targets without removing ARN in notification
