Am I sending junk mail to my friends?

If you don't recognize the email as yours, then you're not the one sending junk to your friends. That may be an online scam or something. The best thing to do is to inform your friends and all your contacts to tag the sender as spam.

I am wondering, though, how it got yours and your friend's contact details. Just to be sure, you can reset your hotmail's password. It happened to me years ago, my friends told me that they saw my YM account will go online at night and send suspicious messages. I did not heed at first but when more friends said the same thing, I reset my password. And everything went back normal.
