I see what's causing the double messages from Deadbeat. Penet puts an X-Anonymously-To: cypherpunks@toad.com into the header that it sends. (I'm not sure why it has to do this; isn't this redundant with the "To:" header?) The cypherpunks mailing list rebroadcaster keeps this header. The mailing list goes to Chael Hall's remailer. That remailer sees the X-Anonymously-To line in the header and thinks this message is a remailing request. (The other Cypherpunks remailers uses a different header line for their remailing requests.) That remailer then obediently sends the mail to Cypherpunks, and so we get two messages. Either Chael's remailer should not accept X-Anonymously-To as its remailing request, or Penet should not put X-Anonymously-To into the outgoing message headers. Perhaps this would be a good time to standardize the supported set of headers for remailing requests. Hal
