To instantly permanently delete

Please add an option, could be a setting for the delete button, to instantly permanently delete unwanted emails.

I get tons of emails that I want deleted, instantly, and not to have to go around accounts and to open all trash folders to empty them.

Just tap delete and gone forever!

This will also reduce the size this application takes on phones.

You can configure the app to not use a Trash folder by changing Settings → [Account] → Folders → Trash folder* to None.
