AWS SES setup - unable to send test mail - amazon-ec2

Question

I configured AWS SES as per this document.
Unable to send mail from a SES 'verified' email id (info#medicovibes.com)
If I run this code from an AWS EC2 instance, I get a blank page or 500 error. no error message pertaining to the problem can be seen.
<?php
// If necessary, modify the path in the require statement below to refer to the

// Tell PHPMailer to use SMTP
$mail->isSMTP();
// Replace sender#example.com with your "From" address.
// This address must be verified with Amazon SES.
$mail->setFrom('info#medicovibes.com', 'rimo ');
// Replace recipient#example.com with a "To" address. If your account

You can try to enable debug in PHP mailer and execute it from CLI.
php filename.php
https://github.com/PHPMailer/PHPMailer/wiki/SMTP-Debugging
You should be able to see where is the problem.
