[support] sending an email after a form submission

Hi, I must make a sort of order form in one of my site. I know how to make a form, or with cck, or with a module called webform. But, I'd like that, after the user submitted the form, he receives a confirmation email about his submission. What is the fastest solution to do this? thanks again. -- Simone Dal Maso.
