A usefull function to send mail

A very usefull function() example to send mail quickly.
Thanks for notice !
The Autoload file with *__autoload()* function, is just used if you don't want to use the requires for each class. This function was included on PHP5 and it doens't work on php's older versions :( so i didn't use it because you maybe using an older php's version for a specific project(like me).
