signing-off is related to a sign-off policy.

In theory a strict sign-off policy would mean that:
anybody who signs a commit signs that the author information is given proper (meaning: to best knowledge)
also often the sign-off indicates that the one who signs a commit agrees to the commit (in a weak sense)
