Thank you for your reply.
I have checked your form, and I found the Sender Email is not setup to firstname.lastname@example.org, as it has to be. This might be the Cause of the issue.
To prevent this kind of issues I will recommend you to check the next guide, which has important instructions: How to setup email alerts to prevent email bouncing related issues.
