A:It depends from where you're receiving it ... and what kind of puter/OS you're using. I have MBP without Windows OS ... and once I mark certain email as spam, next time it lands directly into the Spam folder and gets deleted automatically after few days. If I receive email from site I subscribed, i.e. I gave them my email address, I must unsubscribe first and emails stop. I don't know how Windows based machines operate ... -- icnif77
