But the big ISPs don't need Sender ID

There's no need for the big ISPs to use anything like Sender ID. Because there are not many of them (even including the 50+ menbers of ESCP), they can share round their SenderID-style records very easily. The whole lot will fit on a single sheet of paper. I'd suspect they do something like this already, filtering out purported hotmail addresses that don't come from the correct IP block. And it would reduce the DNS load.

I think nigelm has hit the bullseye with "they could leverage at least the requirement to publish appropriate domain records on the rest of the world if the rest of the world wants to talk to the big provider majority". Think "follow the money".

Have you seen the ESPC's membership list?

The ESPC's membership list reads like a list of organisations whose main interest in getting rid of spam is to ensure that their e-mail is more visible when it lands in your mailbox; the big names on the list are companies like DoubleClick.
