Sorry if I'm being dense - will someone please E-mail me and tell me why outgoing-only (or incoming-address-unavailable) remailers are useful? The original intention of remailers is to allow people _who already know each other_ to do so without revealing that fact to the outside world. I would suggest that this use of remailers, rather than pseudonymity, it much easier to integrate into existing mail software, and would at this point be a good next step. But we don't even have encryption and signing well integrated yet, so I'm not too hopeful today. My criterion for a successful deployment is when the authors of a mailer distribute encryption, signing, and remailing support as a basic part of their packages. True pseudonymity further reduces risk of linking physical identity to online identity, but simply concealing communication patterns accomplishes a lot of that already. Eric
