I just had to tell some people about this discovery as I think it is great. It's a new e-mail server called ippimail.com (ippi is japanese for "helping hand" apparently)
It uses money from page sponsers and donates it to charity. At the moment it has a good list of charities such as born free and muscular dystrophy, and you can select from the list which of the charities you want your e-mails to contribute to. Also as it's new you can get just about ANY e-mail address you so desire(and they dont allow ANY junk mail which is a bonus!)
