Well there is a solution and it has been working with the LUV lists for over a 
year.  The LUV lists use Mailman just like this list.

If you read all the Wiki pages etc and try to set it up from first principles 
and documentation then you will have many problems with DKIM and Mailman.  If 
you do what I suggested in my first message then it takes about 5 minutes to 
get it all fixed.  Change 1 line in a config file, restart the daemon, and then 
change 1 entry in the web based config for the list.

Sounds nice.  Could you publish the configuration in a blog post or write it up 
in a Wiki somewhere?
