It's a limitation of the retainer in the plugin, not a matter of configuration or QoS 1 used. We might address this in RabbitMQ 3.9
where the MQTT plugin will be rearchitected but no promises.

Other brokers such as Mosquitto will deliver message with retain flag set when a client subscribes to a topic with wildcards e.g. subscribing to # topic will deliver retained messages on all topics. Is this broker specific? Can RabbitMQ's MQTT plugin be configured to support that?

I have tried with and without QoS 1.

I'll be happy to test it out as and when this gets implemented. Thanks!
