    Maybe we can put DEBUG before INFO to keep the implicit order

>             Project: James Server
>          Issue Type: Improvement
>          Components: Mailet Contributions
>    Affects Versions: master

>
> 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.
