Please provide a list of all mailman settings you are going to change. I
guess at least the following settings will be changed:
subject_prefix -> <empty>
msg_header -> <empty>
msg_footer -> <empty>
scrub_nondigest -> No
filter_content -> No
What other settings are you going to change?
What about the Reply-To header munging related settings? Is Reply-To
protected by DKIM signatures?
What about include_sender_header ("Should the Sender header be rewritten
for this mailing list to avoid stray bounces? Yes is recommended.")?
