I'm trying to Forward email to an external domain

Any abc.com or gmail.com

but I'm getting a 554 5.7.1 <>: Sender address rejected: Access denied error

I setup a Flat Forwarding in GWIA

Setup a Forward as attachment with nothing but

To: GwDom.GWIA:me@gmail.com

even checked out TID https://www.novell.com/support/kb/doc.php?id=7002601

but still no luck
