Actually, DMARC works fine with mailing lists

Lists should keep the From address, the Subject, and the Message totally unchanged. They should add a Sender header to indicate their relay role, and set at least the List-Id and List-Unsubscribe headers for mailbox rules and subscription management.
This configuration will allow mailing lists to function as proper SMTP citizens in the age of DMARC.
