Receiving "Server Response 554 - Relay Access Denied"

I have reviewed other posts about SMTP and relay related issues. I'm using M2 and have grepped the logs for Postfix - with no success. The Web interface is working correctly. I can send and receive from any of the domains. The issue seems to be sending using one of the additional domains that I've setup.

any help would be appreciated.

Thanks
