ResponseBodyGenerator (acme4j S/MIME 3.3.0 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface ResponseBodyGenerator
```
A generator for the response body to be set to the Message.
This generator can be used to design the body of the outgoing response email. However, note that the response email is evaluated by a machine and usually not read by humans, so the design should be kept simple, and must be conformous to RFC-8823.
The responseBody must be a part of the response email body, otherwise the validation will fail.
A minimal implementation is:
```
 response.setContent(responseBody, RESPONSE_BODY_TYPE);
 
```
Since:

2.12
