We shouldn't have to keep this giant security hole in email (spoofing) just because mailing lists, which predate the spam and spoofing issues, don't want to update how they operate. Accommodating =reject DMARC policy is simple for the mailing lists. A policy of "Because that's the way we always did it" is dumb. We didn't use to recycle, now we do...because it is better. DMARC is better than allowing spoofing. Update your mailing list. Stop forging sender. Move on.
