how to you stop spam mail

It sounds like you want to cut down on the junk mail you're receiving in Mail on your Mac, which is running OS X Mountain Lion. Most email providers will try to filter out spam or junk before it gets to you, as will the Mail application, but they don't always get it all. The article linked below provides more information about that process and will help you customize the filters.
