When connecting via mostquitto\_sub to a RMQ which has virtual hosts, how does one specify that?

MQTT doesn’t have the concept of virtual hosts, so you need to handle it differently in RabbitMQ. The documentation discusses this: [MQTT Plugin — RabbitMQ](https://www.rabbitmq.com/mqtt.html#virtual-hosts)

The mosquitto clients do set an SNI host when using TLS, so you may be able to make use of that.
