The problem you get with this solution and the reason why outbound  
mail comes from the <listname>-bounces alias rather than the  
<listname> alias is that if outbound traffic to your subscribers  
bounces then the bounce messages end up being re-distributed to the  
subscribers, just like regular posts to the list! The bounces alias  
captures bounce messages and the Mailman bounce handler deals with them.
