How do I identify whether the message comes from mailman or list1 or list2? Sorry for the questions, I'm not that experienced so far.
Here are some of the headers of your message as I received it from the mailman-users list with my comments interspersed. How you actually see these headers depends on your mail client. It may be something like "show original" or "view source" or something else depending on the client. I have removed some headers which aren't relevant to this discussion.

If you just get the complete headers from all the duplicates of one message received by one user and post those, I can help interpret them.
