I actually laughed when I saw this topic. A few months ago I got a weird email with an unusual attachment.. I emailed it to my computer, and bam, Norton pwned the email. Apparently it was home to a Win32 Netsky DMM virus, and fortunately I had a firewall. On the other hand, since my sidekick was configured to automatically open emails it had acquired this virus.. I now recieve much more spam than I did before, half of them from the virus sending a email to an invalid address or an person who caught the virus in an email i sent them. Fortunately I don't care and rather enjoy pressing the delete button (wish i could hear that beep)
dunno how computer literate you are, but if its ordinary spam it could possibly have an link at the bottom to 'unsubscribe'. A fun way to get revenge against someone you hate is subscribe their email to a ton of sites, appropriate or not
