Actually, it occurred to me that we have mechanisms whereby domain owners

when you find an SPF or DKIM match.
Ian, the correct way of phrasing it is that SPF and DKIM can MITIGATE
(my emphasis) certain types of abuse of their domains.
I would also point out that someone could deploy an SPF record with a
+all. How does that prevent anything?
