In case this may help someone else.
After some research I have found the Roadrunner has blacklisted all of their ip addresses for SMTP use. So if you are hosting on a Roadrunner public ip then your SMTP will bounce. It doesn't matter if the port is open to your server.
Hmmm...Now all it have to do is figure out how to use Road Runners SMTP server to forward my outbound mail.
