A nice, albeit quite expensive, way of pretection from traffic analysis is to create a mailing list (or a newsgroup) and forward all messages to all users of that mailing list or newsgroup. Of course, since messages are encrypted, only the recipients will be able to decrypt them.

This was discussed here several years ago, under the name "anonymous message pools". Myron Cuperman, the operator of the extropia remailer implemented one, although I don't know if it is still running (I haven't gotten any mail from it for years). It was basically just a mailing list specifically for this purpose, that you would use as your anonymous return address. Of course a problem is that there may not be enough people signed up to provide much privacy protection. Hal
