I'm still betting on something downstream from Mailman. You could
verify this by checking the outging MTA logs on the Mailman server.
You should see all four messages from list1-bounces at ...,
list2-bounces at ..., etc. being delivered to the MX for your test

If you don't have access to those logs or to someone who does, you
could do a test by sending a test message to your test address
directly and to a local address with a .forward to the test address.
I'm betting that in this test, the test address will see only one copy.
