Queues are base_queue, in_memory_queue, bounded_queue, disk_backed_queue, redis_queue, priority_queue, priority_queue_impl, priority_scheduler and queue_manager__queue_manager. Delivery is delivery_manager, delivery_guarantee_manager, receipt_store, replay_engine, circuit_breaker and postman_error_handler. postman_governance_manager (731 lines) applies governance, message_store, envelope_handler and payload_handler handle messages, and postman_config_manager, postman_admin, health_checker and postman_metrics_collector run it. cli starts the standalone router process.
