They're breaking RFC 822 / 5322.
The "From:" field specifies the author(s) of the message, that is, the mailbox(es) of the person(s) or system(s) responsible for the writing of the message. [...] In all cases, the "From:" field SHOULD NOT contain any mailbox that does not belong to the author(s) of the message.
I don't think we should compound that by changing the From line.
Several others have made relevant replies while I was on the plane to Montreal, registering for PyCon, attending the opening reception ...
Anyway, I wanted to say I agree completely with the above even though the DMARC community does not. That's why I implemented the option in 2.1.16 to wrap the original post as a message/rfc822 part attached to a new message from the list.
Unfortunately, when I actually turned this on in response to Yahoo's change in DMARC policy, I got complaints from users of Apple iOS iThings that their mail clients do not deal well with this message, so I reluctantly went the non-compliant mung the From: way.
Yesterday I wrote a brief FAQ on this which is at http://wiki.list.org/x/ggARAQ.
