There is nothing in an ordinary email message, except for the IP
address of the host that sent it to you, that is a reliable
identifier. A validated DKIM signature adds a level of
authentication by identifying the domain responsible for the message.
The main benefit of DKIM is that a validating agent can know who is
responsible for the message. This is more reliable than email
source identification has ever been before. Furthermore, DKIM does
not put any constraints on the delivery path.
The term "responsible for the message" gives the impression of
authorship. How about "accountable for permitting the submission of
the message (by an unknown author)"?
Using the term "who is responsible for" should not be used to avoid
confusion with the message's author. Be explicit about roles. The
benefit of DKIM is that the validating agent can verify the domain
accountable for permitting the submission of the message beyond the
immediate server.
