From: header munging is not done in archives or digests because it isn't
necessary there. (Also see

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

change it.
