how do i delete every mail in my maillbox with postal?

i end up with a bunch of mails that only have notes/letters left after i loot the items

i dont want to loot anything else i just want to delete every mail with 1 click

never touched it, but try playing around with:

New module: DoNotWant. Shows a clickable visual icon as to whether a mail will be returned or deleted on expiry. Allows fast deleting/returning of mail by clicking the icon (bye Lunar festival mail!). Standard popup warnings will still show for deleting items though.
