I have Mailman up and running. I just sent an e-mail to 5 lists and the e-mail came duplicated to the recipients. I checked the header and the only difference is the following:
- Header: X-Spam-Status: No, score=-1.5 required=5.0
tests=BAYES_00 autolearn=unavailable version=3.3.1
- Header: X-Spam-Status: No, score=-1.5 required=5.0

I'm confused. Are you looking at all the headers or just those your MUA shows you by default?
Indeed, I looked only to the headers I recieved (Iceweasel->View->Message Source). Even now I checked those header my wife got, because she and I are in different lists, but received duplicates. Her headers seems identical.
If you look at all the headers, at a minimum, some Received: headers and Mailman's X-BeenThere: header should be different.
How can a avoid duplicates in future? What is the reason?
Normally, if you cross post to 5 lists, people who are members of more than one of the lists will receive a copy of the post from each of the lists of which they are members.
The only way to avoid this is by using the Non-digest options -> regular_exclude_lists feature. For example, if you regularly post a single post to list1, list2, list3, list4 and list5, you could put list2, list3, list4 and list5 in list1's regular_exclude_lists, and put list3, list4 and list5 in list2's regular_exclude_lists, and put list4 and list5 in list3's regular_exclude_lists and finally put list5 in list4's regular_exclude_lists.
Then if a post is addressed to all 5 lists, anyone who is a member of list2, list3, list4 or list5 will not receive the post from list1 and anyone who is a member of list3, list4 or list5 will not receive the post from list2 and so on. See the (Details for regular_exclude_lists) link for more info.
This hint is very useful to me as I have more lists with members that are in more than one list.
But in this dedicated case I wrote to 5 lists where the members are disjunct and my wife, and I got duplicates. I don't know why :-S
I assumed that the others got duplicates too, but I have to proof.
