Configuring Mandrill mail SMTP on Web app hosted with godaddy

Pls check out web app on [login to view URL] We want to send our mails through Mandrill ( transactional mail) SMTP. According to us it is simply a matter of changing few settings/ configurations. We have tried but think we are missing something basic. Below are more details 1) Hosting - GoDaddy (Shared Hosting) 2) Configurations 'mail' => array( 'class' => '[login to view URL]', 'transportType'=>'smtp', 'transportOptions'=>array( 'host'=>'[login to view URL]', // 'encryption'=>'tls', 'username'=>'*************', 'password'=>'************', 'port'=>25, ), 'viewPath' => '[login to view URL]', ), 3) Error Message Expected response code 235 but got code "535", with message "535 Incorrect authentication data " This should be a 1-2 hour job for someone who knows Mandrill, smtp etc or has faced similar problem in past. Willing to Pay upto USD 50 Successful delivery : All mails through the webapp should go through mandrill rather than Godaddy.
