sounds a bit like www.vanqish.com . But other than that, how would it work for mailing lists like this one?
My solution to this would be for people to be able to select certain senders as not being charged.
... which leads to the same problems every e-postage scheme does: * It swaps the current set of problems for an all-new and quite possibly worse set of problems, as bad guys come up with ways to scam the per-message payment system. Just think, get infected with e-payment klez via your fast always-on DSL connection, come back the next day and find that it's sent 50,000 messages so it's spent $1,000 of your money. If you waive fees for virus victims, every spammer's going to claim a virus did it. And maybe a virus really did do it, it's the obvious way to send spam with someone else's stamps. * It turns every ISP into a bank. ISPs don't have the expertise to be banks, nor can they afford the financial exposure. What are you going to do when 10 of your users get e-klez, refuse to pay the postage that the virus stole, and leave you holding a $10K bag? * Nobody in the world has the faintest idea how you could implement 2 cent payments fast and cheap enough to use to pay for e-mail. If you're serious about e-postage, could you let us know what your solutions to these problems are? You may have insights that the rest of us don't, but we'll never know if you don't tell us.
