A remailer is an Internet site to which you can send e-mail for forwarding to an intended destination while concealing your own e-mail address. E-mail sent through a remailer is sometimes known as anonymous e-mail . There may be valid reasons for wanting to conceal your e-mail address (and personal identity) from an e-mail recipient. There are, of course, unworthy reasons, too. However, advocates of anonymous e-mail and remailer services remind us that having the right to conceal your identity in a note can, on occasion, be socially useful and the practice should be possible.
A small number of Web sites provide remailer services. Until it was recently closed, the best-known remailer was the Finland-based anon.penet.fi. It reportedly handled about 10,000 messages a day and had almost 700,000 registered users.
