If you do create an option to let list admins control this setting, I 
would recommend making it default to not available unless explicitly 
allowed by the site admin, and then default to off unless explicitly 
changed by the list admin.

Then I think you want to create some additional loop-control mechanisms 
to help defend the list against dain-bramaged mail systems.  You should 
also test "reply-to-all" functionality with that kind of setting.  You 
could definitely get at least duplicates that way.

I don't have any direct experience with doing this sort of thing in 
Mailman, because the option has never been available (short of modifying 
the code), and I didn't feel it was necessary.

But this concept really does make me cringe.  I'd want to see it heavily 
tested before released.
