[hashcash] 0.4.12 is alive

for reasons completely outside of my control, the camram web site and mailing list have been "helped". While I'm waiting for the right things to happen, I made some updates to camram and have called them 0.4.12

you can find that usual suspects (as well as a significant chunk of history) at http://harvee.org/download/

as usual, raging_dormouse will grab all the right pieces for you and put them in the right places with the right permissions etc. etc. if you need documentation, ask and I shall make it available. Double points for telling me where I screwed up in the documentation.

the primary new feature is a feedback mechanism which definite works server side and has a possibility of working client side. The way it works is given a specified mailbox (maildir or mbox. Others available on request) is considered full of spam. the contents of the mailbox is harvested, sent by XML IPC to a specified server and is used to train system for better recognition.

on a mailbox machine, to this technique can be used with a single person or all persons. Now, this technique also has promise client side because many e-mail clients use standard formats to hold e-mail messages and therefore are amenable to the same technique of harvest and remote delivery.

it would have been nice to hack on Thunderbird to implement a button to do the move from the current folder to the spam mailbox where could be harvested but, I'm trying other finish other projects right now.

help wanted:

1) make a version of camram that runs on devil Linux, fit the whole package on a business card CD-ROM, use usb flash to hold configuration data for users etc. The goal is to make an interception filter (Spam firewall) that is trivial easy to set up and run. I want to model this on IPCop which is a firewall you can set up and have operational within fifteen minutes. Adding moderately complex configurations takes another 20 minutes. I want to do the same for spam barriers.

2) implemented differential pricing model where one can increase the inbound e-mail stamp requirements based on the spamminess of the source address. At a certain threshold, stop accepting e-mail from that address unless it has a big stamp, really big stamp. Reason for this model is that it gives you the benefits of black holes without the negatives. I'm thinking of calling it brown listing.

The basis of Abelard's philosophy, which he taught to Heloise, was
that logic had to be applied to religion in order to arrive at the
truth.
