We already have a voluntary mechanism for the client to disclose

Which is currently unhelpful... because many "trusted" systems don't
use it. So the information it provides is unreliable, in that it
doesn't help distinguish bad systems from good ones.
As a general principle, most systems could handle spam if they
published a policy for accepting spam (# of messages, size, arrival
rate, bandwidth, etc.), and then the spammers *followed* that policy.
Right not, there's no way for the recipient to publish their policy,
and there are few ways for the originator to publish what they intend
to send.
There has been some talk about a generic policy expression mechanisms
for MTAs. The question is how do you enforce it?
