[ale] New form of spam or phising?

[Scott Castaline]

Just received an email with subject of failure notice from 
MAILER-DAEMON at kidsi.net. It appeared that I had sent an email to an 
unknown recipient and it was being returned. I tried kidsi.net on my 
browser (FF3.0b) and it appears to be an Asian based site and 
immediately a large message box popped up making some statement about 
sharing Fedora 9. I cancelled of course, but to be honest I'm not sure 
what just happened. Any ideas?
