That ship sailed a long time ago. There are a number of ISPs which no longer provide email accounts/port 25 services. If a user with an account at one of those domains wanted to use their login as an email address are you suggesting that others should send responses to that "email address" even though no MX is available for that account and mail will never reach that user? It is clear to me that a domain owner/admin has the right to determine how that domain will or will not be used. The individual is not banned from ever participating in a mailing list. They simply can't use an account from that particular domain. There are plenty of other places they can get an email account from. They also have the opportunity to tell their existing provider they are unhappy with policy. Providers can and do change their policies. For the longest time, the address block associated with Amazon Simple Mail Service was a swamp of badness. Legitimate users and organizations started deciding to not use other Amazon AWS services as a result of their mail being blocked. Amazon got religion and started cleaning up their mess. So yes, even large players can respond to market and community pressures. I'm not the person who initially suggested MLMs reject users/email from domains that publish p=reject. That was John Levine. Perhaps he was being sarcastic, perhaps not. It is certainly a forcing mechanism. And that may just be what is needed for domains to think carefully about how they implement DMARC.
