E mail Subscription

Every time I create thread, post comment or someone post on my thread I have received a notification on my e-mail.
I have already set the DEFAULT THREAD SUBSCRIPTION MODE to "Do not Subscribe."
But still I received e-mails. How to turn it off?

I guess no one here knows the answer.
Any [COLOR=#ff0000]MODERATOR [/COLOR]here, kindly help me.

Top right of screen next to My Profile , click on "settings"
next screen click on "View all subscribed threads"
click on "Empty current Folder"

thank you pitch,.. ^^
