Wietse, Thanks for the fast response!
This server does not have IPv6 enabled so in the main.cf I just set it to IPv4 only. inet_protocols = ipv4 I did put your configs in but commented them out for the moment. I have the dkim milter now enabled with the spf. Gmail also lists DMARC as another option to ensure mail goes through so that is next to look at. If there¹s anything else that comes to mind, I¹m all open ears. I¹ll be sure to share any success stories since this seems to be a really BIG issue on the internet with no real solutions.
