That's one way to do permission based e-mail. You can also do cryptographically signed messages with a white list. It's simpler and will in practice be about as effective and less of a pain to use. It's similar to the way that private mailing lists stop spam except better because addresses can't be spoofed as they can in normal e-mail. You forgot 3) Human filtering of spam. Not relevant for e-mail, but relevant for newsgroups and mailing lists. It works on normal moderated newsgroups today. _______________________________________________ Devl mailing list Devl at freenetproject.org http://lists.freenetproject.org/mailman/listinfo/devl >From - Wed May 2 08:53:13 2001 Return-Path: <devl-admin at freenetproject.org> Received: from hawk.freenetproject.org (postfix@[4.18.42.11]) by funky.danky.com (8.9.3/8.8.7) with ESMTP id AAA27002
