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.

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.
