Working with the files that come with the distribution you want to do the following: Empty smtprelay.tab In server.tab put "EnableAuthSMTP-POP3"<tab>"0"
That's it. Anyone or thing that tries to send mail to your server that isn't to a local domain will have to send authentication. >From what you have listed that you did you want to get rid of "Smtp-Config-MyLiveIP" "mail-auth", empty the smtpauth.tab and do the above and you should be where you want to be. If you set EnableAuthSMTP-POP3 to 1 (or leave it out as default is 1) it means that anyone that has successfully POPed mail from the server in the last few minutes can send mail from the same client IP to non-local domains without authenticating.
