So, assuming you are also blocking port 25 connects from the local host
via the loopback interface, you are blocking Mailman's connects to
Postfix, thus preventing Mailman from connecting to Postfix and the
resultant sending from Postfix of whatever Mailman is sending.

Take a look at Mailman's queues, particularly virgin, out and retry to
see what's there. Use Mailman's bin/dumpdb to see an individual
entry's message and metadata or bin/show_quefiles to see one or more
entries' messages.

I suspect the actual network traffic is coming from Postfix sending the
stuff that Mailman is delivering to it. The question is what is
Mailman doing. Check the queues as above and also Mailman's smtp and
perhaps other logs.
