Summary: Encrypt each Anon-To within the previous remailer's message.

[For a step-by-step explanation of remailing with cypherpunk
remailers, see FAQ 3.3.  For an explanation of chaining, see the post
below, or follow John Hull's example:

	<http://saddle.yoll.net/anon/handrolling.html>

An explanation is also in the help file from almost any remailer
(under the heading "REMAIL REQUEST: CYPHERPUNK CHAIN" for most
Reliable remailers).  Send a blank email message to a remailer with
"remailer-help" (without the quotes) as the subject, or see Frog's
Thesaurus Data
<http://www.privacyresources.org/frogadmin/Thesaurus/Thesaurus.html>.

Chaining messages is achieved by repeating the encryption steps.
Taken as an example, chaining through two remailers thus,
You -> A -> B -> Recipient

You start off with your message and prefix with


::
Anon-To: <recipient@somewhere>

##
Subject: <some text>

<MESSAGE>


You then encrypt this with the key of the remailer B, and prefix it with 


::
Anon-To: <Remailer-B@somewhere>

::
Encrypted: PGP

<PGP MESSAGE>


You take this and encrypt it with the key of remailer A, and prefix with


::
Encrypted: PGP


and now send it to remailer A.

What happens then is that remailer A takes the message, decodes it, and
sends it to remailer B. Remailer B decodes it and sends it to the
recipient.
