It's just so easy! I love it, spam and hoax busting is a little hobby of mine. I'm nowhere near as proficient as some of my more determined and technopowerful friends, but I've always delighted in thwarting spammers. Now my little internet sport has become the right of every Australian resident.

SpamMATTERS is a handy little add-in for common email programs, created by the government, for the people of Australia.
You can download it, and the instructions guide one through installation with no grief, though I have to admit I didn't bother reading them, predicting it would be as painless as it was. In default mode, it only reports the offending piece of spam to the Australian Communications and Media Authority. Scrolling down the user guide page after the installation instructions, there is information on how to set it to delete the unwanted emails.
Ahh, the simple pleasures of the internet!
