Email inbox associated with bitcoin address to charge incoming emails

[remotemass]

What if you could associate your email inbox with a specific bitcoin address and tariff any or some of the coming email with specific tariffs?
For example, you could set most incoming emails to free of charge but emails coming from hotmail and gmail would have to send you 10 satoshis a day for them not to end in the trash folder.

You're solving the same problem as hashcash. No one uses hashcash.

Problem with an opt-in proof-of-not-spam option is:
- you can't count on every email provider implementing your scheme
- dropping emails that aren't spam is completely unacceptable
Therefore you must accept emails that don't meet your proof-of-not-spam criteria.

Unless you're saying the sender includes the satoshis; that's potentially more workable. Wherever you provide your email address, you'd need to include a note that you use this anti-spam system; there would need to be a lot of people doing it for the infrastructure for using it to be in place and in the meantime it would be quite a pain for senders, but senders would attach to an email a private key to an address containing your fee. Someone would only need to do this the first time they email you, as once they've reached your inbox once they'll be on your "accept" list unless you've flagged them as spam.
