I'm not entirely sure how Evolution is doing it, but the reliable way to
filter list mail is to look at the SMTP reverse-path, often visible in a
'Return-Path:' or 'Sender:' header, or in the initial 'From ' line of
mbox mail.

List-ID, X-Been-There, Reply-To and other headers all have false
positives.
