DKIM has nothing to do with the rfc5321.MailFrom address or anything else in
SMTP. It is a message-level mechanism, not transfer-level.
The dkimbase signing specification's reference to return-path cautions *against*
including it as part of the signature data.
What are you referring to about "as recommended in the spec"?
