To help manage you email and prevent spam from reaching your inbox, you can set filters that specify how emails meeting a particular rule are handled. You can set filters/rules for the entire hosting account, or for individual email addresses. The filters allow you to discard the email, place it in specific folder, redirect to another email address, and more.
This video tutorial shows you how to create filters for specific email accounts. See the directions below the video for how to create global email filters and other options.
