It also provides full control to the receiver on whether to
"pull" the
data or not, and shifts the burden of storing the data to the
spammers.
It shifts that burden for all email senders.
It seems as if what you want is the ability to read just the headers of an
email message and then decide to reject it.
This is possible in the existing SMTP deployment, just send a refusal code
and slam the connection shut as soon as you detect spam.
