This message is being sent to you automatically in response to the message you sent to with subject "remailer-help". There is an automated mail handling program installed on this account which will take any message in the proper format and automatically re-send it anonymously. You can use Mixmaster, a program specially designed to send anonymous messages in a very secure way. The software is freely available from . If you use Windows, you can use the remailer client software Jack B. Nymble from or Quicksilver from . Messages larger than 10240 bytes are split into parts. Some remailer clients cannot handle these correctly. In this case, it is better to use Mixmaster directly. See below. Mixmaster uses a message format based on RSA and Triple-DES encryption. Messages are multiply encrypted and formatted so as to appear identical to other Mixmaster messages. Messages are sent through chains of remailers. Each remailer removes one layer of encryption, and forwards the message. When the final remailer delivers the decrypted message to the recipient, it is impossible to find out where it came from, even if part of the remailers in the chain are dishonest. Remailers also shuffle messages so that a message coming out could have been any of forty or so messages going in. * The remailer accepts PGP-encrypted messages. You can get the public PGP key by sending mail with Subject: remailer-key to . If you want to send an anonymous message, first create a file with two colons in the first line of your message, and the line "Anon-To: address" in the following line. Follow that with a blank line and begin your message. For example: ================================================================== :: Anon-To: beth@example.org This is some anonymous mail. ================================================================== Then, encrypt it with the PGP key of this remailer. In GnuPG, the command to do this is "gpg -r cmeclax@ixazon.dynip.com -a --textmode -e file". Finally, send a message that begins with two colons, the line "Encrypted: PGP", and a blank line, followed by your encrypted message: ================================================================== From: joe@test.com To: cmeclax@ixazon.dynip.com :: Encrypted: PGP -----BEGIN PGP MESSAGE----- Version: GnuPG v1.0.3 (GNU/Linux) Comment: Made with Geheimnis hQEOAwilWaCvbm/5EAQAhxBe6KMwsbOY3UYWiCQ0iSasvPmOJf3t472b3tPG7zUj OmXgCIVYBqQao7ULsLIgfvj4jDuTGdxWeGdxiniOdy1ENKQpvF9qI5vGeNc7mlu7 TnMt4PlpaGm7CIKj/ZdkByoLgFNfKFVK185fooGu77OIkkg+OrqqXq3Q74wuOTQE AJB8v7MfbVBKdE4BnFSvQdPDjpwzfSKcWqIC44U1jQn7M7hoBDDVYQm08r2WED/C phDJ3mRERxnxwtp5tPXBVo+9Um6Hs4EMmFz8qtrqbWW4O7DeGjs2xdagkfsKLM3n 6Sb1QV34Qscz3xxHK7+EsTXMW4qYFXHP/DV4xK1cvSMOyVuEKbPOE48TNJv4M2PN ziw/71tyvMKvAdAn4fqtVeyQZdQrZNU7ROwe/wy8cuBXFxfQ6efo+j6j1f9kiUjL 7tf86X8aKuc6hV4fl6H2q7ftrxsjom+g2LDdg/xJ =q8qj -----END PGP MESSAGE----- ================================================================== The remailer will decrypt the message and forward it anonymously. A message like thefollowing would be delivered to : ================================================================== From: le cmevi'u ke'umri Comments: This message did not originate from the Sender address above. It was remailed automatically by anonymizing remailer software. Please report problems or inappropriate use to the remailer administrator at . To: beth@example.org This is some anonymous mail. ================================================================== You will often want to include a Subject or other header lines in your anonymous mail. You can insert header lines in the anonymous message by preceding them with a "##" line in the unencrypted file: ================================================================== :: Anon-To: jim@example.org ## Subject: Re: Twofish In-Reply-To: Your message of "Tue, 12 Jan 1999 22:47:04 EST." <199901130247.WAA02761@example.com> This reply is anonymous. ================================================================== Even though PGP encryption is very secure, this still leaves some information open to attackers. For example, if someone gets an anonymous message whenever you have sent an encrypted message to a remailer, it is likely that you are the sender of those messages. You can instruct the remailer to delay your messages for some time or send it empty messages to make such analysis harder: If you use the line "Null:" instead of "Anon-To:", the remailer will discard your message. The "Latent-Time:" header causes the remailer to keep 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. You can, of course, use another remailer to send the message to anonymously. For example, take the message ================================================================== :: Anon-To: cmeclax@ixazon.dynip.com :: Encrypted: PGP -----BEGIN PGP MESSAGE----- Version: GnuPG v1.0.3 (GNU/Linux) Comment: Made with Geheimnis hQEOAwilWaCvbm/5EAQAhxBe6KMwsbOY3UYWiCQ0iSasvPmOJf3t472b3tPG7zUj OmXgCIVYBqQao7ULsLIgfvj4jDuTGdxWeGdxiniOdy1ENKQpvF9qI5vGeNc7mlu7 TnMt4PlpaGm7CIKj/ZdkByoLgFNfKFVK185fooGu77OIkkg+OrqqXq3Q74wuOTQE AJB8v7MfbVBKdE4BnFSvQdPDjpwzfSKcWqIC44U1jQn7M7hoBDDVYQm08r2WED/C phDJ3mRERxnxwtp5tPXBVo+9Um6Hs4EMmFz8qtrqbWW4O7DeGjs2xdagkfsKLM3n 6Sb1QV34Qscz3xxHK7+EsTXMW4qYFXHP/DV4xK1cvSMOyVuEKbPOE48TNJv4M2PN ziw/71tyvMKvAdAn4fqtVeyQZdQrZNU7ROwe/wy8cuBXFxfQ6efo+j6j1f9kiUjL 7tf86X8aKuc6hV4fl6H2q7ftrxsjom+g2LDdg/xJ =q8qj -----END PGP MESSAGE----- ================================================================== encrypt it with the PGP key of the Dizum remailer and send the double-encrypted message to . If you send your messages through a chain of several independent remailers, it will be hard to trace the anonymous message back to you. A much more secure solution, however, is to use Mixmaster for sending anonymous mail. PGP encryption can also be used to receive mail at an anonymous address. Please see , the home page of the nym.alias.net pseudonym server, for more information. * To use Mixmaster directly, type "mix". Note that on Unix, Mixmaster is installed into ~/Mix/ , not ~/bin/ ; you may want to make a symbolic link. You then get a menu in which you can compose a message, send messages from the pool, or quit. When you compose a message, you will get the vi editor, unless you have specified otherwise with the EDITOR environment variable. Be sure to send message from the pool before exiting; otherwise your message will sit in the pool forever. On Windows, you will first have to edit mix.cfg so that SENDMAIL is commented out and SMTPRELAY points to your outgoing mail server. When you run Mixmaster, you will be asked to enter a message with headers included. The message looks like this: ================================================================== To: joe@example.org Subject: test This is an anonymous message. ================================================================== Then hit control-Z and the message will go into the pool. Then type "mix -S" to send it. For more complicated use of Mixmaster, such as specifying the chain or piping encrypted messages to it, type "mix --help" or read the man page. Because unpredictable things often happen to remailers, I recommend that you send each message using three independent chains, by setting NUMCOPIES to 3 in mix.cfg. Only one copy will be delivered, but it is less likely to get lost. Remailers are always appearing or disappearing. See http://lexx.shinn.net/cmeclax/getmix.html for a script to keep your remailer keys up to date. 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 primarily to be harassing or annoying. - Sending large volumes of unsolicited mail. - Flooding Usenet newsgroups. - Denial of service attack. - Use of the remailer for any illegal purpose. If you receive an annoying message, don't ask me where it came from. I have no way to tell which incoming message came out as which outgoing message. If you do not want to receive anonymous mail, send a message containing the line DESTINATION-BLOCK to . To get the remailer's public keys, send mail with Subject: remailer-key or see to get the keys of all active remailers. You can get a list of statistics on remailer usage by sending mail to with Subject: remailer-stats For a copy of these instructions, send mail with Subject: remailer-help to . To reach the operator, direct your mail to . Do not begin your message with two colons, or it will be processed by the remailer and will not reach the operator.
