Need help with email in my Laravel project

I have a laravel project hosted on Hostinger, I am using the Titan email that comes with my Hostinger hosting plan to send emails from my laravel project to users. I do not send a lot of emails. Emails are only sent when creating accounts or events and/or modifying accounts or events. However, the account keeps getting suspended. Attached is the email i received from Titan Support. I am looking for someone to fix this solution for me, If you can fix this solution, I will 100% give you some laravel programming jobs by uploading even more milestones. NOTE: You cant change email accounts. You have to use the noreply at mydomain dot com email account. This way I know the problem has been solved. Send me a message. Let me know you understand this project and you have read the attached support email.
