Probably, as the parts you posted look like standard failure to deliver notices from a receiving mail server. I would guess they are backscatter and the attachments are the original email that they received to deliver. But I am making assumptions so no guarantees. See https://en.wikipedia.org/wiki/Backscatter_(email)
