I'm suggesting some minor changes, only to tighten it up a bit:
There is nothing in an ordinary email message, except for the
RCPT TO line
and the IP address of the host that sent it to you, that is a
reliable
identifier. A validated DKIM signature lets you take some
reasonable subset
of the message you received and know that it came from a
designated source.
The main benefit of DKIM is that a validating agent can know where the
message came from. This is more reliability than email source
identification has ever had before.
I'll give it a try.

any constraints on the delivery path.
