A first message from yahoo.com ( http://www.syslinux.org/archives/2015-January/023060.html )
did arive at my e-mail server, _without_ modified 'From:', _without_ Content-Type: message/rfc822
and _without_ 'Reply-To' header.

I have pressed (again??) "submit" in the mailman web interface,
loaded another mailman admin webpage, reloaded the page 'dmarc_moderation_action'
and have seen the setting 'Wrap Message'

As in "Let it happen". There will be messages from domains that
have DMARC policy "reject". I have you such an address, use it. Try to do
two things at the same time: Regular postings and "test DMARC postings".
