A Trial Balloon to Ban Email?

I think that any loading of e-mail with computational tasks has to follow the
paradigm of the current system, where A sends mail to B and there is absolutely
no other communication betwen B and A or C for that matter.
For instance, take an assymetric algo, where t=Hard(x) and x=Easy(t).
x is something that B can verify is (almost) unique to the message, like
x = (B's e-mail address) + timestamp (must be within last n hours).
A burns cycles to do t=Hard(x) and sends t with the message to B.
B verifies x with x=Easy(t) and accepts or rejects message based on that.
The drawback is that sending any mail costs time. I queue mail and in few
minutes t is computed and mail sent. It could be as little as minute per
message to discourage spam.
No intermediaries, no communication protocols.
