Does anyone really do anything useful with said reports though? In my experience... In the first week you identify a web server or two some marketing team put together with a contact form that you never realised spoofed your domain and never got past SPF filters. After that, you get hundreds of alerts a day about some server in China sending spoofed emails to a server in Vietnam, neither of which you can do anything about.
