Mailman 2.1.16 and up already has the ability to either mung the From: header or wrap the original post in an outer message From: the list.
The major problem is it requires site configuration action to make this option available to list owners.
Given that the whole site is at risk, should it be an option for list owners at all?
Jim P's branch mentioned in his post at https://mail.python.org/pipermail/mailman-users/2014-April/076383.html is a general implementation for posts From: any domain with a reject DMARC policy.
We are talking about this at PyCon now.
Good to hear, wish I could be there! I'll try to be in #mailman off and on 00:00 UTC to 15:00 UTC.
