From remail at tamsun.tamu.edu Tue Jul 13 23:19:46 1993 From: remail at tamsun.tamu.edu (remail at tamsun.tamu.edu) Date: Tue, 13 Jul 93 23:19:46 PDT Subject: REMAILER HEADERS Message-ID: <9307140619.AA11420@tamsun.tamu.edu> Some of you know the sender of the below message, please don't blow my cover, I'm testing the remailers and people's knowledge of message id's (if that would even be an accurate way of tracing the message). Cypherpunks remailer addresses and headers from those sites appear below. If you can trace the origin (sender) of this message please send me mail personally rather than to the list. I'm using my favorite remailer here and I want to make sure it's working right. I have sent mail to the below sites as a test for anonymous remailing returns and to see what headers I get back. It has been maybe 4 days now since I began this experiment, some of the sites below have still not remailed my test message. My main curiosity in this quest is to determine what each header will look like when the mail is recieved. I think this is important in determining which remailer to use. The below is the list of remailers with the "unique header to remailer" info below each site number. If you wish to discuss this matter further, please send a follow up message to the cypher list with your address included and "Re: Unique header". I'm really not too concerned about remaining anonymous, I just want to see if this scheme is really airtight! Thanks! -z A typical mail header looks similar to the below: (I have removed the date, time, etc. to protect my privacy) >From rebma!remailer at kksys.mn.org Thu Jul x 00:38:01 1993 Received: by ahost.some.school.edu (5.57/Ultrix3.0/cc-ix.mc-1.5) id AA02491; Thu, x Jul 93 19:00:54 -0500 Received: from kksys.mn.org by uum1.mn.org with bsmtp (Smail3.1.28.1 #3) id m0oE6Du-00007JC; Thu,x Jul 93 00:21 CDT Received: from rebma by kksys.mn.org with uucp (Smail3.1.28.1 #13) id m0oE5jG-0007TsC; Thu,x Jul 93 00:50 CDT Received: by rebma.rebma.mn.org (Smail3.1.28.1 #1) id m0oE6nS-0002CzC; Thu, 8 Jul 93 17:58 PDT Message-Id: Date: Thu, x Jul 93 17:58 PDT To: me at myhost.some.school.edu From: nobody at rebma.rebma.mn.org Subject: 9 Remailed-By: Mr. Nobody Status: O ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Check out the pub/cypherpunks directory at soda.berkeley.edu (128.32.149.19).
