This servlet uses code from my home made toolbox that you can find in the folder 8/tools and 8/beans.
The toolbox is not ready yet, I have been working for it for a couple of years when I have time.
The goal is to get a toolbox of classes so it will be easier to map tasks to
use-case-diagram.

This servlet get emails from some server that the user decide.
