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.

There is a minor bug in that this is also applied to posts to
LIST-owner, but that is fixed for 2.1.18.

The major problem is it requires site configuration action to make this
option available to list owners.

See the thread starting at
for lots of info.

See the post at
for links to the patches.

Jim P's branch mentioned in his post at
is a general implementation for posts From: any domain with a reject
DMARC policy.

We are talking about this at PyCon now. At sprints starting tomorrow, we
will be working on enhancing the current options by merging at least
ideas from Jim P's branch, and making the switches available to list
owners by default, all with an eye to releasing this in 2.1.18 in weeks.
