I know how to create a filter and once it's created it will execute this filter on all incoming mail. However is there a way to execute this filter on what I already have received?
Go to the list of filters in Settings, edit the filter you want to run, don't change anything, and before you click Update Filter, check the box that says "Also apply filter to [x] matching conversations".
