This mailing list is doing it right, so it is a non-issue for postfix.org 
<http://postfix.org/> mails because:

1. RFC5322.From is using postfix.org <http://postfix.org/> domain.
2. Postfix.org <http://postfix.org/> domain does not have DMARC policy 
published.

All mail from this mailing list will not be DMARC evaluated. 
Authentication-Results header should yield "dmarc=none", when DMARC evaluation 
is not performed.
