It's a helpful document. what it lacks, though, is advice concerning which options to set to turn off modifications that will likely break signatures.
I've searched the Web but without finding good and reliable guidance. What I have found suggests that one should:
1. turn off munging of the subject line.
2. turn off changes to the message body, e.g., text appended to the message by the mailing list.
I just created a mailman list (wanted for other purposes) and tested it. the following changes enabled me to send a message to the list which was posted via the list without breaking the DKIM signature. subject_prefix = '' msg_footer = '' Other relevant options were left as per Mailman defaults, e.g., msg_header = ''.
