Its easier for me to track down who their provider is and demand that their service get cancelled and that they be indentified to me so that I can bill them for the spam. If their provider refuses, then I can just refuse all traffic from that providers routers.

remailers that support spam will get their services cut by their own providers, or will get embargoed by ISP's that won't tolerate such crap.

If its from a throwaway, then there is a dialup ISP that I can pester for ID info on the spammers, and likewise embargo them if they don't cooperate.

What is legitimate but fake? Oh, you mean impersonated? Like how I have the address of my dialup on the From here, but my reply to is my firstname.lastname@example.org address. Someone might put my email address in their header. Gotcha. If the mail didn't come from there, then it really should get bounced because of a conflict between the header info and the routing info.
There needs to be some capability to track it, if not then we need to create a hunting season on spammers to keep the population in check...
