Having been an ISP (destek.net) for many years, it isn't all that
difficult to filter traffic going through a network. It is done all the
time.

I have to ask this one question: why e-stamps? It seems a solution

That certainly seems to be the attitude of the systems I've seen.
However e-stamps do address an ISP concern (namely, they don't get
reimbursed for incoming email, and they can't charge the user, but the
user doesn't *want* most of the incoming email). Of course hashcash
type solutions don't address that. Just e-stamp solutions where the
final MTA actually gets real money.
It seems to me the whole idea behind stopping spam would be for ISPs
to levy a "use tax" on email being sent. Right now the reason spam is
so prevalent is
This assumes that ISPs have control over the email being sent. If all
ISPs did (and all ISPs wore white hats), then we wouldn't be sitting
here. From the white-hat ISP perspective, outbound spam is a bug in
their security. e-stamps won't fix that.
