Pre Mailman 2.1.16, there is no way to do this via list configuration.
It can be done with a custom handler (See
<http://wiki.list.org/x/l4A9>), but if you have the access required to
install such, you are better off upgrading to Mailman 2.1.18-1 and using
it's dmarc_moderation_action or from_is_list settings to change the
From: header rather than anonymous_list.

These options will preserve the display name in the From: header and
put/add the original From: address in the Reply-To: header.

In Mailman 2.1.16 and 2.1.17, only the from_is_list setting is available
and only if enabled by the site.
