There are server which permit you to recant sent mail if it has not been downloaded by the receiver yet. These are unusual. And this technique called superb permit this but it's the only one I know of and it is not hugely available.

If you need to review what you really sent, then observe in the sent folder and also check in trash folder of your e-mail program.
