Mailman sends mail with an envelope sender (Return-Path:) of
LISTNAME-bounces at example.com.

Mailman doesn't rewrite From: headers unless the list is configured as
anonymous in which case the From: is rewritten to LISTNAME at example.com.

If you are sure these messages are coming from Mailman, post the
complete raw headers of a message here, and we'll try to figure out
what's going on.

Note other headers you will always find in messages from Mailman

X-BeenThere: LISTNAME at example.com
X-Mailman-Version: x.x.x
Precedence: list

And headers you may find depending on list configuration
