That sounds like an SMTP-Auth issue. In the GUI go to "Server 
Management" / "Network Services" / "Email" and make sure "Enable 
SMTP-Auth" is ticked. In your case you can pretty much check all 
checkboxes that are in the "Basic" tab - except fort "Enable Z-push", 
which you don't need.

Then make sure the service "saslauthd" is running:

systemctl status saslauthd

If it is, then relaying for authenticated users should work.
