Extracting from the abstract of a paper in process by Casey Deccio (now researching SPF at BYU, formerly at Cisco):

We also find that 75% of organizations with mail > servers for popular domains share DNS infrastructure with up to tens of > thousands of others. Most of his focus has been on SPF but it would be useful to loop him into the DMARCbis discussions. --Kurt On Tue, Apr 21, 2020 at 9:11 AM Scott Kitterman <[email protected]> wrote: > There is probably protocol improvement work that should be done based on: > > https://www.usenix.org/system/files/sec20fall_chen-jianjun_prepub_0.pdf > > Scott K > > > _______________________________________________ > dmarc mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/dmarc >
