Restart postfix by going on panel Manage Services| Manage Postfix and toggle off then on. I have had some issues when restart server postfix wont start automatically.
All good

Much appreciated. Doing that is resulting to the emails flowing for a little while then the problem starts
Look logs if you see reason who postfix stops
