My first impression was that that was just a joke. Then I thought it might be a very good idea after all. Then I thought it surely wasn't a joke, but also wasn't a very good idea. Now I'm not sure. :) It seems like it might be a good idea. All the anon remailers could watch a certain newsgroup, alt.remailer.submit perhaps, and take messages with a "anon-remailer-attn: specific@remailer", and deal with them just like normal mail input. Would there by any benefit to doing this at all over the present system? Why would someone submit a message to the remailer "bramble" via newsgroup instead of just mailing it? Unless you find an anonymous way to post to the newsgroup in the first place, your security seems to be seriously compromised. Even if everything is encrypted, you've made traffic analysis a huge amount easier. And if you are finding a way to post the a newsgroup anonymously in the first place, odds are you have some other entry point to the remailer bramble, so why make a stop on the newsgroup opening yourself up to traffic analysis? Now that I think about it, it seems that there isn't really any reason for such a thing.

For a long time I've wanted to set up a remailer that instead of just re-mailing the input mail would telnet to port 25 on a specified machine and spoof the headers exactly like you tell it to, or that would anon-ftp upload the "mail" message to a specified site, or that would continualy check a local (or remote) ftp directory for filenames that match a certain wildcard, processing them as inbound mail... I can think of a couple of situations under which having a mailer pick up off a newsgroup would be very usefull... send a pgp encrypted, nested message through a chain of four remailers... one is a standard-ish remailer which peels off the first layer of encryption and posts your message to a certain newsgroup. The second one, whos address remains a mystery, spoofs or remails the message it found in the newsgroup to a different newsgroup, where it is again picked up and decrypted by the third remailer, which uploads it to an ftp site watched by the fourth, again anonymous remailer, who picks it up and remails it to the recipient. It may all be an excercise in futility, I'm not an expert on that kinda thing, but it sure /seems/ more secure to me...
