Hashcash and other systems that rely on some sort of check summing is going to cause problems and hence their adoption is always going to be under a cloud ! For me the best possible thing to do is to put up a openbsd server with postfix / clam av / spam assassin / amavaris combo 1. postfix will reject 90% of the spam during the initial handshake stage - by using a variety of dns / mx resolution tricks 2. clamav and spam assassin integrate into postfix so that you don't have to accept the spam the server can even issue a 550 in the middle of the data stage 3. using some known blacklists like spamhaus and rbl will cut down spam to 99.9 % With a combo of all this : no spam - we do not have to worry about our address being leaked. ________________________________________________________________________ Delivered using the Free Personal Edition of Mailtraq (www.mailtraq.com) _______________________________________________ Full-Disclosure - We believe in it.
