Hi Recently people have sent me pointers to new bits of software related to hashcash, and I've just updated the hashcash.org site to point to them. Here's a summary of new things: - hashcash support for novell netmail MTA via it's agent plugin framework http://netmail.sourceforge.net/hashcash.html - built-in hashcash support in chrysanth mail manager as of version 2.0 (chrysanth is a windows client side anti-spam system for cleaning pop box without downloading) http://www.hashcash.org/mail/spam/chrysanth/ - another fast hashcash minter (not got code yet, waiting for response) -- interesting to see if there are any new insights / compare to Jonathan's techniques - apparently spamassassin 3.0 should be out soon (hmmm it is using version 0 format... so much for moving to version 1 any time soon) Adam
