This could also be an attempt to get a mailing list to work.
i have seen few mails get dkim fail from apache.org, very few, but its not normaly not dmarc fail for me on this, what is worse is that opendmarc have still brokken spf support :(
even google does not care in reports
There's a continuing problem with email list traffic getting bounced by DKIM, and various work-arounds - the gist is that the mail has to come from the list manager, but you still need a way to indicate the original author of the message. Hacks abound. But basically, DKIM is just broken.
i have added patch to opendmarc that ignore domains that have policy reject on dmarc if its a known maillist sender mta, this way i would stay on maillists and have policy reject, if i turn down to quarantine policy, people would not see the forrest for trees
i will still keep postfix maillist never breaked dkim for a good reference
