This is my understanding as well. In theory I believe a mailing list can change some headers but I was never able to get that to work so I a simple (non-mailman) list I have replaces the from header, appended is what I do and it results in something like:
From: "'Craig Leres' via Fnord Mailing list" <fnord@example.com>In mailman2 I think the setting is "from_is_list":
Replace the From: header address with the list's posting address
