I guess by "secure authentication" you probably mean forcing use of TLS, and requiring SMTP authentication (something like permit_sasl_authentication after/without-preceding permit_mynetworks), then probably yes. To be sure, you can try to test your host as open relay from outside your network (something not listed in mynetworks).
