These hea= ders shouldn't be included by default if they aren't set on the original outgoing message. Is there a page we can point people to that explains why these defaults are wrong and how to properly setup the exim MTA to do dkim signin= g? If I understand Ian's comment #6 these misconfigured dkim defaults are not common and we could just ignore them. People will just get periodically unsubscribed till they fix their dkim setup to not include empty Sender or List-* headers. But it would be nice to apply From rewriting to help such misconfigurations. There is a recipy for Exim to do that in comment #6. I don't know if that c= an easily translate to postfix. --=20 You are receiving this mail because: You are the assignee for the bug.=
