I'm running mailman version 2.1.22.
reply_goes_to_list is set to poster

Documentation describes "Munge From" to be
"This action replaces the poster's address in the From: header with the list's posting address and adds the poster's address to the addresses in the original Reply-To: header."
This means that messages with a munged From: header should pass dmarc checks but the senders address will be added to the reply-to header. Does this not mean that the Reply-To: and the To: address will be the same for some users?
Well, depending on how the user crafts the post, many things are possible, but with from_is_list = Munge from[1] and the usual situation, the post is
From: Joe Sender sender@example.net To: A list list@example.com
and after munging the delivered post is
From: Joe Sender on behalf of a A list list@example.com Reply-To: Joe Sender sender@example.net To: A list list@example.com
Reply-To: is the sender's address sender@example.net and To: is the list address list@example.com. These are not the same.
[1] It is recommended to set from_is_list to No and dmarc_moderation_action to Munge from. The resultant munging will be the same but will only be applied to messages From: a domain publishing a DMARC policy of reject (or quarantine if dmarc_quarantine_moderation_action is Yes).
