HI Oracle Learning Team, Thank you for courses. I attended few java courses before from 2006 to 2019 in other places. But I am not happy with quality. I feel If I learn Java directly from Oracle Java Training Providers, Learning quality will be good. I am happy about the introduction part of the course and step-1. I am happy to explore more and learn the all the steps in the course. I hope my doubts If any will be clarified by Oracle. But the Oracle email Id (curriculum_feedback_ww@oracle.com ) given in Course enrollment confirmation email is not working. I got error response as "Address not found Your message wasn't delivered to curriculum_feedback_ww@oracle.com because the address couldn't be found, or is unable to receive mail" Please solve the problem If possible. Thank you
