Question : Exchange 2010: 530 5.7.1 Client was not authenticated

I have a 2010 server and trying to get it set up.

I see through some of the posts that the receive connector needs to be adjusted in order to receive email from an email address outside of the organization.  I have modified the default connector. See attached image.

Are there any other places where I need to allow inbound email?
