This mail message was sent automatically in response to the message you
sent to help@alpha.c2.org

This system allows you to create a pseudonymous address of the format
username@alpha.c2.org.  For security, all messages are encrypted with PGP.

To create a mail alias, first create an encrypted reply-block for a
cypherpunk-style remailer.  An encrypted reply block is a message
encrypted with a remailer's PGP public key, which will be sent to
your address, or to an address where you can receive messages.

To create a reply block, you would create a message for a remailer that
goes back to you:

 ::
 Request-Remailing-To: you@yoursite.org

Then you would encrypt that with a remailer's public key, and prepend
the necessary Encrypted: PGP header.  When this message is received by
a remailer, it would decrypt it and send it to you.  It would also send
you any text appended to the end (outside the PGP wrapper).  Thus, using
a reply block, it is possible for people to send you mail without knowing
your real address.

Next, choose a pseudonym and a password.  The pseudonym-address may contain
any alphabetical or numeric characters, or hyphens.  The password may not
contain any spaces.  Then create a message of the following format:

 From: yourname@alpha.c2.org
 Password: Your_Password
 Reply-Block:
 ::
 Anon-To: remailer@utopia.hacktic.nl

 ::
 Encrypted: PGP

Do not actually indent it.  It is indented here because some people's
mailers try to auto-decrypt PGP messages and this is just an example.

Encrypt this with the following public key and mail it to
alias@alpha.c2.org.  Unencrypted mail sent to this address
will be deleted automatically.  If everything is correct, your
mail alias will be created, and you will be sent a confirmation.
If not, there will be no way for the software to reply to you,
so the message will be deleted.  If you don't receive anything,
something is wrong, so try again.  Be sure to test the reply
block first, so that you will know it works!  Also, don't forget
to include the address of the remailer, and the Encrypted: PGP
header at the beginning of your reply block.

A note about the Password header: Upon receiving the first message
from a particular pseudonym-address, the password is set to whatever
is in the password header.  You must include this SAME PASSWORD in
EVERY SINGLE MESSAGE that you send to alias@alpha.c2.org from that
particular pseudonym-address, until you change the password using
New-Password.  If you sent a message to create a new address, and
did not reveive a reply, and then you realized that it was because your
reply block is not working, you have already set your password, so
you must include the same password when submitting the new reply-block.

Here is the public key:

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: 2.6

-----END PGP PUBLIC KEY BLOCK-----


When mail comes in for your address at alpha.c2.org, it will be
encrypted with Your_Password, using pgp -cta, appended to the reply
block and sent to remailer@alpha.c2.org.  Be sure that you have
the Encrypted: PGP header, and the address of the next remailer
it is to be sent to!  All messages are held and sent out in random
order once an hour.

If you later wish to change your password, send an encrypted message to
alias@alpha.c2.org containing a From: line with your nickname, a
Password: line with your current password, and a New-Password: line
containing your new password.  If the old password is correct, the
password will be changed to the new one.  For example:

 From: Dan_Quayle
 Password: Bush
 New-Password: Clinton

You can set a new reply block in the same manner that you did when you
first created your address, but your request must contain your current
password.

A mail alias can be deleted at any time by setting the password to nothing.
(Send a password change request with nothing following the 'New-Password:')


Sending messages

Once you have created a working address, you can send mail from that address.
Simply create a message with standard mail headers, and add your password
in a Password header.

 From: jdoe@alpha.c2.org (John Doe)
 Password: foobar
 To: alt.anonymous@news.demon.co.uk
 Subject: hello world

 This is my message.

Encrypt this and mail it to alias@alpha.c2.org.  The message would be
delivered as shown, minus the Password: header.  If the password is not
correct, the message is discarded.


Troubleshooting

Here are some common problems.  If you're having trouble, check the
following list:

 - Be sure to use -t option with PGP
 - Test your reply block and be sure it works!
 - If you are having trouble creating a certain address, perhaps
   you already created it, but used the wrong reply block
   or a different password.
 - Usenet posts require a Subject: header.
 - Messages to alias@alpha.c2.org must be encrypted with PGP
   Be sure you use the correct PGP key; remailer@alpha.c2.org
   has a different one.
