I was curious by Scott comment re SPF.
Is there a class of spam that cannot get a DKIM signature?
I would think botnets would be that class, as they usually infect computers and not sure they could DKIM sign as it would require them to set a DNS entry too. Knowing that botnets are 70% of spam, if DKIM could solve this one it would be great.
so my question to add to your question "Does the presence of a signature provide any objective data about the goodness or badness of the signer?" is:
is there a class of spam that cannot get a DKIM signature?

Does the presence of a signature provide any objective data about the goodness
or badness of the signer?
If the claim is that it does, there needs to be an explanation of the basis,
because I don't see it.
