29. What is an anonymous remailer? An anonymous remailer is a system on the Internet that allows you to send e-mail anonymously or post messages to Usenet anonymously. You apply for an anonymous ID at the remailer site. Then, when you send a message to the remailer, it sends it out from your anonymous ID at the remailer. No one reading the post will know your real account name or host name. If someone sends a message to your anonymous ID, it will be forwarded to your real account by the remailer.
