The system sending the mail signs it. That's one of the great advantages of DKIM, the signature doesn't have to match other header addresses such as To: or From:. A user whose domain publishes adsp=discard couldn't successfully use such a service, but that's a limitation of ADSP, not of F2F mail or of DKIM.
