Thinking about this we can enhance this rnum a lot by adding the LogWritter
as a field:
```
public enum LogLevel {
Debug((logger, message) -> logger.debug(message)),
...;
private final LogWritter logWritter;
// Constructor & getter
}
```
That way we can no more need LogMessage::selectLogWriter

> Key: JAMES-2171
> URL: https://issues.apache.org/jira/browse/JAMES-2171
> Project: James Server
> Issue Type: Improvement
> Components: Mailet Contributions
> Affects Versions: master
> Reporter: Tellier Benoit
> Priority: Major
> Labels: easyfix, newbie
>
> Today, one can use the LogMessage to generate log messages upon mail reception
> But the LogMessage have the following limits:
> - It do not let you configure the warn level
> - It does generate several logs. One would be simpler to review.
> - It does add some unneeded informations, like mail name already carried by
> the MDC
> - It does not allow logging of specific headers or specific attributeNames.
> This leads to missing information as well as "to much information".
> - The code quality of the mailet is poor.
> You will:
> - Ensure a single log message will be generated. For this you will call the
> logger one time and concatenate log messages parts.
> - Remove the log line with mail name.
> - Add a **level** configuration option. It can takes value **warn**,
> **info**, **debug** or **error**. It will be used to set the logger log level.
> - Add a **specificHeaders** configuration option. It takes a comma separated
> list of header names to include in the log message. By default it is empty.
> - Add a **specificAttributes** configuration option. It takes a comma
> separated list of attribute names to be included in the log message. By
> default it is empty.
> - **body** configuration option should be false by default
> - **header** configuration option should be false by default
> - **init** should propagate exception while initilizing (Integer parse
> exception, also passing a negative max body should throw.)
> - Remove inlined affectation for field. They can be unset on their
> declaration and set when init is called.
> Correct *LogMessageTest* accordingly.
> Don't hesitate to reach us on the *gitter* chat if you have any question.
