These notes from when we used MD to make a workaround for this issue before Mailman also implemented workarounds might help:
mailman breaks dkim, its not yahoo's fault
# BLOCK IF FROM YAHOO (AND OTHERS) BECAUSE THEY SET DMARC TOO STRICTLY
thats not the problem
http://www.pcworld.com/article/2141120/yahoo-email-antispoofing-policy-breaks-mailing-lists.html # REWRITE THE FROM HEADER AND OTHER FIELDS PER RECOMMENDATION HERE: http://dmarc.org/faq.html#s_3
do i need to read it ?, if dkim was never breaked by silly maillists software the problem with dmarc reject policy is gone
possible i am unfair now ? :=)
