Michael,

I don't share this position. In my opinion it is better to not break  
DKIM signatures
where ever possible. Of course there are other options to make a  
message pass DMARC but
but that requires you to update mailman at first.

And, to be honest, configuring a list like suggested makes not only  
'some' messages pass DMARC.
In fact I saw no failure reports for my messages anymore since  
amavisd-users¹ and dovecot² moved to that mode.
