Mixmaster anonymous remailer

A mixmaster anonymous remailer is a type of email service that helps users send messages without revealing who sent it. It works by taking a message and sending it through a series of remailers, which are computers that forward the message through several different steps so that the original sender's identity can't be traced. The message is scrambled at each step to further protect the sender's identity. In the end, the message is received with its original contents but no obvious path back to the sender.
