how can i easily stop junk e-mails without opening them to get address to add to instant delete list?

Sign in to yahoo mail & click on spam folder on left pane. Enable spam guard protection ON. Click on edit setting. Check the box which says' delete all messages immediately on receipt'.. Save the setting & sign out.

Now, your Junk email folder will remain empty all the time.

just click the box add to spam or bulk mail dont open them dont resend your name or email that just puts your name on the list more is best just to hit the spam or send them to bulk mail... surfing and leaving your email will get you this stuff more.... is a lot of spy bots and spy ware that do this is why people get mad about it get a better spyware program and dont fill out anything at any place you dont want mail from helps some..... sucks sometime i get like 200 or so a day
