[Mimedefang] IMPORTANT MIMEDefang List Moved to lists.mimedefang.org

[Joseph Brennan]

        # Mailman always changes messages enough to break DKIM, so if


        # there are DKIM headers in a message we must remove them.


        if ($RelayHostname =~ /(mailmanprod01\.cc\.columbia\.edu/) {

            action_delete_header('DKIM-Signature');

            action_delete_header('DomainKey-Signature');

            action_delete_header('X-Google-DKIM-Signature');


Note... The Mailman host shown there no longer exists.
