It's getting control of your mail flows that is the difficult part for most organizations interested in implementing. I think the real issue for "slow adoption" is lack of perceived need, until you believe your domain is being abused. What is the uptake for DNSSEC? For most IETF standards other than very core ones, the long tail is indeed very long. My gut tells me, based on being in this space a long time, that the overwhelming majority of people aren't thinking about DMARC, let alone the "mailing list problem"/ Michael Hammer
