Email Sending and Delivery Failure on OpenCart 3.0

Email Sending and Delivery Failure on OpenCart 3.0

Hello,

I have tried setting up my email on OpenCart 3.0 so that I will be able to receive emails from customers and customers can also get emails when they order an item.

I have tried all the necessary details listed in setting up email account in the OpenCart version 2.0 and nothing seems to work.

Below is a screenshot of the settings in my OpenCart admin panel. What have I not gotten right yet?

Will appreciate a prompt help please.

Thanks.
