未找到“smtpTransport”类

I am using CakeEmail to send mails on my website, below are my config file info

public $default = array( 
        'host' => 'smtpout.asia.secureserver.net', 
        'port' => 25, 
        'username' => 'xxxxxx',
        'password' => 'xxxxxx', 
        'transport' => 'smtp',
       // "tls"=>true
    );

It is working fine in my local computer but it is giving the below error on godaddy shared hosting.

Class "smtpTransport" not found.

Error: An Internal Error Has Occurred.

According to CakePhp's DOC the class is SmtpTransportnot smtpTransport

Autoloader is case sensitive
