You can click on the number at the top of the message, to bring up the contact page, and at the bottom it should have a block number.
Then you can right click (control+click, two finger click on trackpad) on the message on the left side panel, and select Delete, it should then bring upon a dialog box with the option to delete it and mark as Spam.
