Anonymity: Remailers: Cypherpunk remailers

If you want to mail messages without even an anonymized return address on it, then you should use a cypherpunk remailer. You can encrypt the messages sent to the remailer, and the remailer will decrypt them and send them on to the recipient, whose address is hidden inside the encrypted message. This means that someone who monitors your outgoing mail can't see who you are sending anonymous mail to. For even more security, you can also chain remailers, in other words use more than one remailer to send your message. Now not even the remailers you use know who is sending mail to who. Some remailers even allow you to post to Usenet.

[=] Chaining remailers, an example (By Alex de Joode)
Chaining is using more than one remailer to send a message. Basically, you send a message to remailer A with instructions to send it to remailer B, which in turn finds instructions to send it to remailer C, and so on. When for example A is in the USA, B is in the Netherlands, C in Finland and D in Cuba, tracing it back to the original sender may be a bit of a problem.

[+] Remailing over the WWW
An alternative to "normal" remailing is using a WWW site to remail your messages. It is not recommended if your message is very important, but if you want to try out remailers, then a WWW interface can be helpful.
[+] Security: Encryption: Pretty Good Privacy
PGP is a file encryption program which is generally considered unbreakable. It is used extensively on the Internet, available for almost every platform and is required for anonymous remailers. It can also create digital signatures, which makes it easy to detect forgeries.
