ACMA has implemented the SpamMATTERS reporting and forensic analysis system to help fight spam. A SpamMATTERS reporting ‘button’ is available for download and installation into the Microsoft Outlook and Outlook Express email programs. Once installed, users can simultaneously delete their spam and report it to ACMA with one click of their mouse.
This is for Australians only at the moment, I will find out more from a friend of mine who works for the ACMA. Then I will let you know if this will work for other countries as well...
