Codeigniter SMTP电子邮件错误

Question

I can't get my emails to send when using SMTP with my codeigniter app.

There are many similar questions on SO, but none that solve my problem so that's why I'm asking again.

Here's the error i'm getting:

Here's my config/email.php:
<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');

$config['useragent'] = "CodeIgniter";
$config['protocol'] = "smtp";
$config['_smtp_auth']   = TRUE;
$config['smtp_host'] = "smtp.zoho.com";
$config['smtp_user'] = "donotreply@cjbuilders.info";
$config['smtp_pass'] = "mypassword";
$config['smtp_port'] = 465;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = "text";
$config['charset'] = "utf-8";
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = TRUE;
$config['bcc_batch_size'] = "200";

?> 

Here's my controller snippet that sends the email:

// sends the email to 
$this->email->from('donotreply@C&JBuilders.us');
$this->email->to('myemail@gmail.com');
$this->email->subject('Request from C&J Builders Contact form');
$this->email->message('From: '.$this->input->post('name')."\n".
              'Email: '.$this->input->post('email')."\n".
              'Phone: '.$this->input->post('phone')."\n".
              'Message: '.$this->input->post('message')."\n");
$this->email->send();
echo $this->email->print_debugger();

对于SSL，将ssl://添加到SMTP主机地址

$config['smtp_host'] = "ssl://smtp.zoho.com";
