IIRC Glen from AMSL reads this list, in which case the message has already reached the right ears. As for possible remediation, if the lists are implemented as local aliases(5) in the ietf.org Postfix server, then assigning an "owner-" alias to the list is sufficient to avoid trouble with SPF and simple forwarding should not break DKIM or DMARC. The aliases(5) file (or its database representation) would then contain something along the lines of: document.all: author1@a.example, author2@b.example owner-document.all: postmaster@xxxxxxxx -- Viktor.
