You can use PGP to encrypt messages sent to this remailer if you for
some reason are unable to use the Mixmaster client software. However,
while PGP will securely encrypt the content of a message that you are
sending to the remailer, submitting messages to the remailer that are
merely PGP encrypted without the use of the Mixmaster client software
greatly increases the risk of third parties being able to determine the
identity of the sender (you).

This remailer primarily supports the ability to submit messages for
remailing without requiring the Mixmaster client software for backwards
compatibility with older remailer client software.

If you are able to use the Mixmaster software with your operating system
(chances are you can), it is highly recommended that you use the
Mixmaster client software instead. See the earlier section in this help
file on how to obtain a copy of the Mixmaster client software.

If you cannot use the Mixmaster software, want to use an anonymous
remailer, and are willing to accept reduced security, you can do the
following:

Send email with Subject: remailer-key to <%RMA> to obtain
a copy of the remailer's PGP key.

Then do the following:

1)      create a file containing your message
2)      insert a BLANK LINE as the first line of the file
3)      Insert a "::" as the second line of the file
4)      Insert "Anon-To: final_recipient@destination_domain.com" as the
        third line of the file.

At this time, the file should look as follows:

==================================================================

::
Anon-To:  final_recipient@destination_domain.com 

This is some anonymized email.
==================================================================

5)      Now encrypt the file with the PGP key of this remailer.

Finally, email the encrypted file to <%RMA> as
shown in the example below.

The line "Encrypted: PGP" instructs the remailer to decrypt the message
and process its contents.

==================================================================
From: remailer_user@sender_domain.com
To: %RMA
Subject: anonymous message

::
Encrypted: PGP

==================================================================

Even though PGP encryption in itself is very secure, not using the
Mixmaster client exposes some information to parties desiring to
compromise your privacy. This information leakage permits what is known
as "traffic analysis". For example, if someone receives anonymous
messages soon after you sent encrypted messages to a remailer it is
likely that you are the sender of those messages.

To partially compensate for this information leak, you can instruct the
remailer to delay your messages for some time or send the remailer empty
messages to make such analysis harder:

If you use the line "Null:" instead of "Anon-To:", the remailer will
simply discard your message.

You can add a "Latent-Time:" header to the remailer to retain your
message for some time before forwarding it.  "Latent-Time: +2:00" would
delay the message for two hours. You can use a random delay by adding
"r", for example "Latent-Time: +5:00r" would delay the message for up to
five hours. For example:

==================================================================

::
Anon-To:  final_recipient@destination_domain.com
Latent-Time: +2:00

This is some anonymized email.
==================================================================


You can chain remailers by using another remailer to send the message to
<%RMA> anonymously. For example, take the message

================================================================== 

::
Anon-To: %RMA

::
Encrypted: PGP

-----BEGIN PGP MESSAGE-----

==================================================================

Next, encrypt the message with the PGP key of the %RMN
and send the twice-encrypted message to <%RMA>.

Similar to a nested Russian matryoshka doll, containing increasingly
smaller dolls inside the each outer doll, you can layer multiple
encryption layers and remailer hops around your message. If this sounds
confusing, just use the Mixmaster client software instead.

If you send your messages through a chain of several independent
remailers, it will be become increasingly difficult, though not
necessarily impossible, to trace the anonymous message back to you. A
vastly more secure solution is to use the Mixmaster client software to
send your anonymous mail.

Some remailers supporting PGP encrypted messages offer pseudonymous
"nym" service that allow you to not only send emails privately, but also
receive emails without enabling the sender to determine your recipient
destination email address. For more information about such nym services,
