To be more specific, we will make use of the mailman option dmarc_moderation_action set to "Munge From". For sender domains with a strict DMARC policy (p=reject or p=quarantine), the From address will be rewritten to the list address and the original sender will be in Reply-To. This will avoid bounces when the receiving mail server follows DMARC policies. To avoid invalidating DKIM at all, we would indeed need to remove the footers.
