We give the list owners and site administrator the option of choosing 
how to configure their lists.  So, the choice of who to send the bill to 
would end there.


And to really solve the backscatter issue in this case would require 
that we integrate tightly enough into the MTA that the processing could 
be done while the sender is held open.  The options in that space are 
mostly specific to a given MTA, although postfix also supports the 
sendmail milter interface in addition to the preferred policyd method.

If you wanted to be of service to the community, you could always write 
a milter in Python that would go through all the same checks that 
Mailman would do and indicate back to the MTA whether or not the message 
would be accepted.
