This is the first time in months that my hotmail, now renamed Windows Live Mail has caught a junk mail, that too supposedly from microsoft.com! Seeing this email filtered as junk mail, I think I can now rely on microsoft's spam filtering system. And I can tell you, it definitely works. ((The filtered email was definitely a junk mail - I checked! There was a link with a .exe file, which obviously doesn't affect me much as I use Mac OS.))
Windows Live Mail's spam filter in action!
