Mailman doesn't do this, and it's not a bad idea.  Of course, the best
you can do is prevent indirect spam within the same Mailman instance. 
Another approach would be to set up a "suspicious header" hold on
"Message-ID: <mailman." which is always added by the routines that
Mailman uses to send out mail.  IWBNI you could actually configure
Mailman to drop such messages.
