Has anyone calculated the increased server load, the extra storage needed for the now lengthened outgoing mail queue, and the extra bandwidth required to handle all this extra back and forth puzzle thing? YahooGroups and the like would definitely be impacted. It would be interesting to see what protections will be built into the puzzle thing as well... I can see some joker setting up his server to require that the sending computer calculate PI to some ridiculous number of decimals... although that might make a good honeypot. Or, if the puzzle is open source (which would be a good thing), how soon before the spammers (or even legit MTA authors) hardcode the answers into the server software? I suppose there would have to be some random elements. It is interesting.... as an extension it might be nice to be able to set up a "whitelist" of trusted servers that don't have to go through the computational gyrations to send you mail - that way it would, hopefully, eventually impact the spammers more than it would impact legitimate e-mail servers. -- Jeff Shultz Loose nut behind the wheel.
