OK, Things are going better as I'm no longer being seen as a spam source (long story) short answer was smtp banner and reverse DNS issues.
New problem. When using mx-toolbox it's saying I'm a possible open relay. Initially it indicated I wasn't but I wasn't passing any emails either. Fixed the email issue under Webmin - Postfix-General options changing local networks from 127.0.0.1 to all attached networks. After that change is when mx-toolbox started reporting as an open relay.
Should I have changed this or should I have left it alone and either added the network address or just the upstream source (firewall) address?
Open Relay
Re: Open Relay
You allowed all traffic from all hosts so yes you created an open relay.
Use EFA-Configure (login with ssh) and use the mail settings option to add your domains (http://efa-project.org/documentation/po ... l-domains/)
