Add an account identifier, and the problem is nailed.Ah, so you're saying that only the reputation of individual e-mail addresses is worth paying attention to? How do you expect that to scale to billions of messages per day?
Without authenticating an identity, it must not be used in a reputation assessment. Currently this is commonly done by using the remote IP address authenticated through the action of transport. In the name space there are two options, the HELO and a validated signature. DK and IIM are attempting to allow the signature solution to scale. -Doug
