It seems part of what you intended to post above is missing, but the FAQ
article at <http://wiki.list.org/x/4030534> probably addresses this.
The underlying issue is messages are sent with the envelope sender, an
Errors-To: header and a Sender: header set to the listname-bounces
address. This is so non-delivery notices (bounces) are sent to the
list's bounce processing address and not to the list itself or the
poster of the original message.
It is normally the Sender: header which is exposed by some MUAs
(Microsoft Outlook and other Microsoft products in particular) which
causes user confusion. It actually should not be necessary for Mailman
to set the Sender: as any compliant MTA will return a non-delivery
notice to the envelope sender, but not all MTAs are compliant. In recent
Mailman versions, if the site doesn't disable it, there is a General
Options -> include_sender_header setting that can tell Mailman not to
add it's Sender: header.
