One more thing I want to clarify, if I unchecked "Enable authentication". I would get "Access Relay denied" error even inside the same subnet. Is that I need to manually to add the subnet in the "Access" file of postfix to get it relay successfully if I don't want the user to do the SMTP authentication?
Bind it to the error case I encountered, is that mean the Authentication setting can only control the relay inside the valid subnet. Even I check the Authentication, I still need to add the authorized subnet into the "Access" for the relay?
