SES with CPanel Roundcube

Hi all, So I have Cpanel installed. I have verified the domain and even the email address of said domain. But for the life of me I can not get the email to send. It bounces. Now I have cleared with the AWS safety team to open port 25 as I have found. And it still will not send or receive. Is there additional steps that I need to do...?

I am just trying to setup emails on SES so the client can use them. Thanks LG
