Here i will show you some of the header. The mailman version is not included. And you see, that the administrators of this list don´t understand the difference from ...-request and ...-bounces.

This mailman installation has non-standard patches/code.
In standard GNU Mailman, both Errors-To: and Sender: as added by Mailman will be to the listname-bounces address. Here they go to -owner and -request respectively, so the most likely explanation for multiple Sender: headers is the installation's modified code doesn't remove the Sender: headers before adding its own.
