There is a tool called DCC (http://www.rhyolite.com/anti-spam/dcc) that uses a similar concept in a way. -Alberto -- Alberto Begliomini Email: aub () coldstone com Coldstone Consulting, LLC Voice: 650-654-5938 Security, Systems and Networks Administration Fax: 650-631-8722 Marcus J. Ranum wrote:
Out of 30 messages in the input queue yesterday 30 were spam. 27 of those were korean or chinese. I'm trying to think of ways to deal with spam E-mails and have been kicking around a few ideas with some friends of mine. Most of the truly effective ways we can imagine to deal with spam rely on spam-knowledge propagation: in other words a human being someplace in the mix says "this is spam" and based on that determination causes the offending message to disappear from all mailboxes. So, a side effect of this approach is a 'web of trust' with respect to noise email. :) Suppose I tell the mail system "I trust Dodge Mumford's judgement regarding what is spam" then my mail system will automatically move into my spam folder all emails that Dodge moves into his spam folder. We might choose to look out for eachother in a reflexive relationship, or we might choose to additionally trust an outside source, etc, etc. It occurs to me that this would be pretty easy to implement, with a bit of small extra kludgery. You could build it right into an imap server by having it apply the extra processing when someone moves a message into a folder called "spam" - in fact this way _one_ person in an organization could keep an up-to-date set of Eudora filters that would be leveraged by everyone in that spam trust ring. Does anyone know if this is already being done? Does anyone see any really compelling reason it wouldn't work?mjr. ---Marcus J. Ranum Chief Technology Officer, NFR Security, Inc.
