Hi,

maybe using Bitcoin for email postage could reduce email spam?

A possible solution for reducing spam would be to take a fee for sending emails.
Even the smallest possible amount of 0.01 USD/EUR/GBP... would cost the average spammer to much money so that spamming wouldn't be profitable.

Problem with offline cash is that transaction fee for very small amounts is inadequate.

Maybe Bitcoin could be an alternative?
How could it work?

What's your opinion?
