The whole idea that email can be reliably authenticated back to a domain is sort of new. Mailing lists are still trying to figure out how to fit into this brave new world. However, the bug that Franck alludes to is just that -- a bug. When list operators are supplied with upgrade paths that solve these specific problems, the issue becomes "how to get software upgraded", which is nice. Brass tacks: Run your domain with "p=reject" if you're confident that you've covered all your legitimate email w/ DMARC. Tell the world that your email is real and that you've taken time to make it easy for receivers to drop fake stuff. If you're on an important mailing list that is impacted, tell the operator that you'd like to continue to use DMARC. They probably don't have the tools to do the right thing, but first step is raising awareness by actual users.
