Well, i am not exactly sure what are the minimum changed required to make
DMARC happy, i never run a DMARC compatible list myself. Looking through
the lists i subscribed to there maybe even some way to leave From intact.
Quck googling says that ezmlm added some DMARC support started with version
7.2.0, so you may try to talk to the list admins about it.
