在godaddy共享服务器上配置codeigniter smtp

Question

我已尝试过以下代码并不断收到此错误

  

无法使用PHP SMTP发送电子邮件。您的服务器可能未配置为使用此方法发送邮件。

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'mail.keytimeng.com'; //change this
$config['smtp_port'] = '25';
$config['smtp_user'] = 'info@keytimeng.com'; //change this
$config['smtp_pass'] = 'xxxx'; //change this
$config['mailtype'] = 'html';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
$config['newline'] = "\r\n"; 
$this->email->initialize($config);
