Chaining Cypherpunk Remailers

So, we use a remailer and our email address and name are not visible in the email itself and cannot be retrieved from it, but the path our message takes is possibly a simple one: it goes from the sender directly to the remailer, which sends it straight to the recipient. Obscuring the path a bit more can increase the level of anonymity and security a bit further. To do this, we should use not one but a number of remailers in a chain. If we want to use 3 remailers in chain the process would be as follows: we send our message to remailer A, which forwards it to remailer B, which in turn forwards it to remailer C. The latter then delivers our message to the intended recipient.

Chaining remailers is easy.

Chaining is just like sending mail using the email body to specify the recipient of the anonymous email (for more info read Specifying the Recipient for Cypherpunk Remailers). We just have to make sure there are two colons at the beginning of the remaining body, followed by the next address in the chain. This means that the chain is mirrored at the beginning of the message body as a list of remailers where each remailer is represented by two colons followed by an email address and finally a blank line. So, each remailer in the chain strips its two colons (followed by the address and the blank line) from the body and forwards the remaining email body to next address.

We want to send an email to mail@address.com, and we want to send it highly anonymously. So, we send it through three remailers.
The first (fictitious!) remailer shall be AAA@anonym.com, the second BBB@invisible.com and the third CCC@hide.com.

From: "Email Privacy" admin@emailprivacy.info
To: AAA@anonym.com
Subject: TEST
::
Request-Remailing-To: BBB@invisible.com

::
Request-Remailing-To: CCC@hide.com

::
Request-Remailing-To: mail@address.com

The first remailer, AAA@anonym.com removes the first two lines and will forward the message to BBB@invisible.com. This second remailer will get a mail looking like this:

From: BBB@invisible.com
To: CCC@hide.com
Subject: TEST
::
Request-Remailing-To: CCC@hide.com

::
Request-Remailing-To: mail@address.com

BBB@invisible.com sends the message on to CCC@hide.com, which eventually delivers the message to mail@address.com.
