I would like to expand on Hal's suggestion that remailer operators post their policies on a)keeping logs and b) divulging same.
The anonymous mailing system at pax has the following policy: - A log of activities of the remailing software is maintained when debugging is in progress (often) which could be used to correlate real identities with aliases - this is no more or less information than is available in the alias database which is not visible to anyone except the root user. Message-id's are NOT stored in this log, and the contents of messages and posts are NOT stored anywhere, nor are they scrutinized by me or anyone else. I don't care and I don't want to know. If someone does something unreasonable and I get complaints then I could lock out a particular source of mail if I didn't get a good explanation, but I am not going to go reading other peoples mail in order to censor it ! - Under no circumstance short of being arrested and/or the equipment commandeered by someone else will the alias database be divulged or the contents or routes of messages deliberately intercepted. david
