As far as I am concerned if it could be done w/ a neural network, or

Ouch. Neural networks are _deterministic_ (except, possibly, analog VLSI ones such as Mead's). Digital neural networks can't do _anything_ that cannot be done by algorithms; they run on Turing machines too. Why neural networks are 'magical' as Perry says, in certain classes of problems, is that they provide a way to perform complex algorithmic funtions through a relatively simple interface to humans. In any case, how "fuzzy" do you allow your relative magnitude function to be? Even if a function exists that compares keys with a magnitude difference of the order of 100 bits, it's useless. For your binary search method to work, this comparator function would have to be accurate when the difference is on the order of just 1 bit. Yeah, quantum computers ;-) ----------------From owner-cypherpunks Mon Jun 20 10:33:41 1994 Return-Path: <owner-cypherpunks> Received: by toad.com id AA20571; Mon, 20 Jun 94 10:33:41 PDT Received: from src.honeywell.com (moon.src.honeywell.com) by toad.com id AA20548; Mon, 20 Jun 94 10:33:24 PDT Received: from tbird.src.honeywell.com by src.honeywell.com (4.1/smail2.6.3/SRCv0.25); Mon, 20 Jun 94 12:33:26 CDT id AA02136 for cypherpunks@toad.com at toad.com Posted-Date: Mon, 20 Jun 94 12:33:15 CDT Received: by tbird.src.honeywell.com (4.1/SMI-3.2) id AA29883; Mon, 20 Jun 94 12:33:15 CDT Date: Mon, 20 Jun 94 12:33:15 CDT From: bergstro@src.honeywell.com (Pete Bergstrom) Message-Id: <9406201733.AA29883@tbird.src.honeywell.com> To: cypherpunks@toad.com Subject: re: MAIL: secure mail Sender: owner-cypherpunks@toad.com Precedence: bulk

What I've tried is to do a "|pgp -feat ecarp|rmail erc%khijol@apple.com", but pgp just produces empty files! If I execute it by hand, it works. Anyone know either (1) why it isn't working wnd how to fix it, or (2) suggect a better alternative?

The problem may be this: pgp needs a path.

Try "| PGPPATH=/whatever pgp -feat ecarp | rmail erc%khijol@apple.com"

This is what I needed to do when I tried something similar with mh and slocal.

Keep in mind that if you have a site that follows CERT advisories, there are usually restrictions on which programs may be used to filter mail. My site requires a sysadmin to put an entry in a config file to allow any filter programs to work at all. One standard filtering program that works well is procmail. This will typically be "approved" by default and should keep your (Ed's) admin from having to be involved in your incoming mail. Pete
