That log entry is about TLS and has nothing to do with SMTP AUTH. It's easy enough to confirm that SMTP AUTH is working by using a standard mail client to send a message to an external domain. You might want to configure and test the submission service on port 587 as you do this, because it is customary to restrict this service to authenticated users and exclude $mynetworks (so being on the same network is not likely to pose a problem). In most cases, you can uncomment the submission service in master.cf and use the defaults. Run your tests, then check your log for lines containing sasl_username or sasl_method. There are also tools available to check your configuration, depending on what type of authentication you're using.
