This message is being sent to you automatically in response to the message
you sent to [e-mail] with subject "remailer-help".

This is a Mixmaster remailer. It provides an extremely high level of security.
To use it, you must have a client program to produce the messages.
This software is available from ftp://nately.ucsd.edu/pub/remail,
or if youre outside the US ftp://utopia.hacktic.nl/pub

Read the README file for instructions. In the US this file is export
restricted, so it can not be retrieved directly.

Some information can be sent to you by the remailer by including the
following commands (one per message) in the subject line of mail to the
remailer.

  remailer-help         This file.

  remailer-stats        Useage statistics for the last 24 hours.

  remailer-key          The mixmaster key file for this remailer.


A list of remailers is available from ftp://nately.ucsd.edu/pub/remail,
http://nately.ucsd.edu/~loki/, and will be posted periodically to
alt.privacy.anon-server and other privacy related groups.

TYPE1 remailer-help

I have an automated mail handling program installed on my account
[e-mail] which will take any message with the proper headers
and automatically re-send it anonymously.  You can use this by
sending a message to [e-mail], with the header Anon-To:
<address>, the address that you want to send anonymously to.  If you
can't add headers to your mail, you can place two colons on the
first line of your message, and then the Anon-To line.  Follow that
with a blank line, and then begin your message.  For Example:

> From: [e-mail]
> To: [e-mail]
> Subject: Anonymous Mail
>
> ::
> Anon-To: [e-mail]
>
> This is some anonymous mail.

The above would be delivered to [e-mail] anonymously.  All
headers in the original message are removed, with the exception of
the Subject (and Content-Type, if present).  She would not know that
it came from Joe, nor would she be able to reply to the message.
However, there are a few ways that the true identity of the sender
could be found.  First, if many anonymous messages were sent,
someone could compare the times that the messages were sent with the
times that 'joe' was logged in.  However, this can be prevented by
instructing the remailer to delay the message, by using the
Latent-Time header:

> From: [e-mail]
> To: [e-mail]
> Subject: Anonymous Mail
>
> ::
> Anon-To: [e-mail]
> Latent-Time: +1:00
>
> This is some anonymous mail.

The message would be delayed one hour from when it is sent.  It is
also possible to create a random delay by adding an r to the time
(ie +1:00r), which would have the message be delivered at a random
time, but not more than an hour.  It is also possible to delay the
message until a specific time.  For example, "Latent-Time: 18:00"
would delay the message until 6 PM, Central European Time.  Times
must be in 24-hour format.

Another problem is that some mailers automatically insert a
signature file.  Of course, this usually contains the senders email
address, and so would reveal their identity.  The remailer software
can be instructed to remove a signature file with the header
"Cutmarks:".  Any line beginning with the same text at in the
cutmarks header, and any lines following it will be removed.

> From: [e-mail]
> To: [e-mail]
> Subject: Anonymous Mail
>
> ::
> Anon-To: [e-mail]
> Cutmarks: --
>
> This line of text will be in the anonymous message.
> --
> This line of text will not be in the anonymous message.

This Cutmark feature can also be used to post a delivery notice
to a specified newsgroup. {ie. alt.anonymous.messages}]

> From: [e-mail]
> To: [e-mail]
> Subject: MSG-id 1994.11.31
>
> ::
> Anon-Post-To: alt.anonymous.messages
> Cutmarks: *
>
> Message <1994.11.31> succesfully remailed
> *
> ::
> Anon-To: [e-mail]
> Cutmarks: --
>
> ##
> Subject: Anonymous Mail
>
> Hi This is some anonymous mail
> This is in
> --
> This is out

If the first message shows up at misc.test you know that the message to
[e-mail] succesfully was remailed.

For added security, you can encrypt your messages to the remailer
with PGP.  The remailer software will decrypt the message and send
it on.  Here is the remailer's public key:

-----BEGIN PGP PUBLIC KEY BLOCK-----

To utilize this feature, create a message with two colons on the
first line, then the Anon-To line, then any other headers, such as
cutmarks or latency, then a blank line, and then the message.
Encrypt this with the remailer's public key.  Then send it to the
remailer, adding the header "Encrypted: PGP".  If you forget this,
the remailer won't know that it needs to be decrypted.

Any unencrypted text after the PGP message is also remailed.  This
is to allow sending to someone who is anonymous.  If you create a
PGP-encrypted message to yourself via my remailer, and then you give
it to someone, they can send you a message by sending the encrypted
message to the remailer.  The remailer will then decrypt it and send
it to you.  The message gets anonymized in the process, so the
sender will need to include a return address if he wants a reply.

You can use this remailer to anonymous post a message, the syntax
for that is:

> To: [e-mail]
> Subject: ignore
>
> ::
> Anon-Post-To: misc.test
>
> Test of anon message posting

You must specify a Subject, if no subject is specified the newsserver
will reject the posting. Please donnot use the "Subject: test" if testing
to a test group [ie. misc.test] but use "Subject: ignore blabla" instead.
That will prevent my mailbox from being swamped with test replies, those
are send automaticly to -any- test posting with test in its Subject-line.

For non-anonymised postings the syntax is:

> To: [e-mail]
> Subject: ignore
>
> ::
> Post-To: misc.test
>
> Test

The remailer "understands" the following commands:
anonymous remailing : {Anon-To: ,Anon-Send-To: ,Request-Remailing-To: }
non-anon  remailing : {Send-To: }
anonymous posting   : {Anon-Post-To: }
anon-anon posting   : {Post-To: }
discard part of mail: {Cutmarks: }
time fideling       : {Latent-Time: }
PGP encryption      : {Encrypted: PGP}
Header Pasting      : {##}, {below that you add your header info}

You can get a list of statistics on remailer usage by sending mail
to [e-mail] with "Subject: remailer-stats"

A ping-list of anonymous remailers is available by fingering
<[e-mail]>.

This remailer is endorsed by Replay and Company UnLimited, however
they donnot approve or condone the content of remailed messages.
I, Alex de Joode, take no responsibility for the content of posts or
messages, and I take no responsibility for the consequences of using
my remailer.  For example, if you post anonymously, and someone
manages to trace it back to you, I am not responsible.  Also, I have
no way of screening mail that goes through this remailer, so I am in
no way responsible for the content of posts or mail going through.
Also, note that this remailer is experimental.  Its mode of
operation is subject to change without notice.  Users are advised to
check these instructions and to do test messages often.

Abuse Policy:
I consider the following to be inappropriate use of this anonymous remailer,
and will take steps to prevent anyone from doing any of the following:

- Sending messages intended primarilly to be harassing or annoying.
- Sending messages intended primarilly to sell a commercial product.
- Use of the remailer for any illegal purpose.

If someone is doing something inapropriate with this remailer,
please send mail to <[e-mail]>, as soon as possible.
The problem can only be solved if the operator is aware of it.

If you don't want to receive anonymous mail, send me a message, and I
will add your email address to the block list.
