To the penet knowledgeable: is my understanding correct?
It depends on the remailer. Mine, for example, sends messages with a From: line of "eli-remailer@jarthur...", and some others do similar things. I believe this address already has a penet address. I have no problems with chaining from here to penet, though I suggest making it clear that 1) attempts to reply will result in an ugly bounce, and 2) the persona using the chained ID can be identified only by continuity of digital signature. IMHO, this is useful way of bumping the anonymity level up a notch over posting directly with penet -- an attacker needs both penet's lists and a bunch of sendmail logs. Others, including Julf, may feel differently, as this provides some degree of "hit-and-run anonymity". PGP 2 key by finger or e-mail Eli ebrandt@jarthur.claremont.edu
