You just give find for me the best tool i searched for almost 5 years. A simple way to use (smtp) mail testing on a windows machine... (i never arrived to configure any mail tool on my windows machine)
The test mail server tool !
One click install, and it works ... wonderfull !
About Netbeans : i'm currently testing many IDEs. It could be my final choice. I just found that the java machine was memory killing with that IDE (500Mo used ...) ooops ! quite a lot ! But for all other features, i like it !
