Using SRS, is it possible to "fake" a bounce, to cause the forwarder to think it's a bounce from something it sent, when in reality the spammer is using the forwarding system to relay to anyone and everyone? Or is that what the cookie is all about?

Yes, that's the purpose of the cookie. If you receive something that looks like a bounce but doesn't have the appropriate cookie, you assume it's been faked and just discard it instead of passing it along.

I'll leave the rest for someone more familiar with SRS.
