From: header munging is not done in archives or digests because it isn't
necessary there. (Also see
<https://mail.python.org/pipermail/mailman-users/2017-September/082470.html>)

In short, it can but we won't because it would cause your posts to be
rejected by every recipient whose ISP honors DMARC.

Because your list option "Avoid duplicate copies of messages?" for this
list is set to Yes (the default). If you don't like that, go
to<https://mail.python.org/mailman/options/mailman-users>, log in and
change it.
