All Implemented Interfaces:

I2CPMessage
```
public class MessageStatusMessage
extends I2CPMessageImpl
```
Defines the message a router sends to a client about a single message. For incoming messages, it tells the client that a new message is available. For outgoing messages, it tells the client whether the message was delivered.
