So? So use list-id when it exists, and filter on non-standard things when it
doesn't. List-ID is guaranteed unique and to not change. Sender -- isn't.
Yes, Sender is useful when the List-ID isn't there, but if you depend on it,
stuff like this happens.

That's why List-ID was invented and why Mailman supports it.
