Stopping spam at the root

Based on the spoofing and general deceitful tactics now utilised by spammers, how does one trace an email (emails) back to the original sender. Whether that sender is an infected machine (adware) or the culprit himself.

Then, how much sense would this suggestion make:
Can we start a list of all emails and domains from which these vermin are launching their annoying pestilence and make that available to mail software companies and individuals (basically anybody who wants it) so we can really fry spam!

I’m distressed!!!!
