Which messaging destinations are accessible externally from a Mule app?

Explanation:
The ability to be reached from outside depends on the transport being used. VM endpoints are an in‑memory, intra‑runtime transport; they exist only inside the Mule runtime and aren’t exposed to external systems. To interact with Mule from external applications, you’d use a JMS transport connected to a JMS broker. Among JMS destinations, topics support publish/subscribe and can be accessed by external producers and subscribers connected to the broker. Therefore, JMS topics are externally accessible, while VM destinations are not.
