I'm sorry. I just don't see where this is feasible.
Other than
deployment, I don't see this as much of a problem.

How does the recipient of that email establish a consent framework
for communication with you? How does he separate your traffic from
the "forged spam" traffic?
This is a good question. This is something that would have to be
resolved by the people who are proponents of this solution.
I don't see this sort of solution being feasible. The legitimate
third-party relay problem is a tough one to solve.
How does the recipient distinguish "legitimate" third-party relays
from "illegitimate" ones?
See above. I don't have any answers. I can say that I think
this will be one of the more difficult problems that will have to be
resolved, in order for this kind of proposal to succeed.
I'm not opposed to legitimate third-party relaying. But it's my
perogative as a recipient to discard any email I choose.
Sure. You can throw away your e-mail any way you want.
However, before you can expect that a significant number of
people will adopt this kind of system (thus allowing you to use it to
filter your mail), the problem of legitimate third-party relay will
have to be solved. People will not want to use any system that has
such a serious problem with collateral damage.
Unverifiable
third-party relaying is a large part of my spam, and costs me time and
money.
Then you should set up filters now that require that the envelope
sender address matches the domain portion of the reverse DNS for the
sending MTA. Start throwing away as much e-mail as you possibly can,
as soon as you possibly can.
Meanwhile, the rest of us will continue to work to try to find a
system that would be feasible to recommend to the rest of the people
in the world.
