@Mark Berry, thanks for the link to Valimail but it wants me to sign up so I will consider doing that soon.
FYI, the DMARC reports only specify?how?a message or set of messages pass or fail (DMARC, DKIM or SPF) as well as originating server IP but provide no message details beyond that. This may be why Valimail provides no other details. By the way, MxToolBox has an excellent??for the reports you will receive.
