How to get delete email?

How do i get rid of the question "do you really want to delete all mail" when i delete multiple email in yahoo?

• just another action every time i delete mail

• Answer:

  You can't change or get rid of it. It is a courtesy notice offered by Yahoo (and every other mail program), sort of a warning that you are about to "permanently" delete items. That notice only appears when you're deleting from the Spam OR Trash folder---- both of which ARE permanent deletions. No chance of ever getting anything back from either place,( just in case you change your mind later).
