I’m not very knowledgeable on the subject but it occurred to me that in order for SPF and DKIM to do their job the DNS server needs to provide the records to the email receiving server. Does or can the DNS server record that access and if so could I be notified of that access (a sort of delivery notification). If that access is recorded what are the potentials for misuse, could a spammer get enough information from a temporary DNS server to confirm delivery addresses. I’m not expecting any answers but it was one of those thoughts that once I had it wouldn’t go away.
