But the answer to the first question is not correct. I have some people in different mailman maillists with 2 Sender fields. And because my mail client Thunderbird use the first then the filter don´t work. I had to extend the filterlist with the "Sender" field.
In Mailman 2.1.14 and newer, there is an include_sender_header setting on each list's General Options page. If that is Yes, Mailman will remove all Sender: headers from the incoming mail and add its own. If it is No, Mailman doesn't remove or add Sender: headers. Pre 2.1.14 Mailman always did removal and addition.
Maybe, i can also use the field "List-Id". It can work for the same. And in all this mails with the double Sender field i see only one List-Id fields.
There is also an Errors-To: header and there should always be just Mailman's.
Never i have checked other mails for 2 Sender fields. I can do it, if it would helpful for you. And if you need the mailman version, i will look for.
If Mailman is adding a Sender: header without first removing any existing ones, I would like to see all the headers from such a message as sent by Mailman.
If i should make a bug report, tell me. And, because it is the first time for me, give me some tips how i should do it.
Bugs in MM 2.1 should be reported at https://bugs.launchpad.net/mailman/+filebug, but first, just send me or post here the full message headers from the message as sent by Mailman.
