Codeigniter SMTP Email Error

问题:

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:

hello:

From: 
Return-Path: 
To: [e-mail]
Subject: =?utf-8?Q?Request_from_C&J_Builders_Contact_form?=
Reply-To: "donotreply@C&JBuilders.us"

Email: [e-mail]
Phone: [phone]

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'] = "[e-mail]";
$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('[e-mail]');
$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();

For SSL add ssl:// to Your SMTP host address

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