How To Filter Spam Mail

[phil72]

I'm getting a lot of junk mail in my live. com account actually 99% is junk, can't figure out how to get the junk mail blocked, i hardly use this account anymore due to this but need it as I still do get important mail at times.
I need a spam filter or apo for my GS3,its stock not rooted (yet) if anyone knows of any good app that will work please let me know.
