Codeigniter SMTP error

Question

I'm trying to send emails from my CodeIgniter application via Zoho SMTP server.

Here is the code: $this->load->library('email');

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'smtp.zoho.com';
$config['smtp_user'] = '<username>';
$config['smtp_pass'] = '<password>';
$config['smtp_port'] = 465;
$config['smtp_crypto'] = 'ssl';
$config['mailtype'] = 'text';

$this->email->initialize($config);

$this->email->from('<mail>', '<name>');
$this->email->to('<mail>');
$this->email->subject("Test");

$this->email->message("Test message");

if(!$this->email->send()){
    echo $this->email->print_debugger();
}

And I get this output:

220 mx.zohomail.com SMTP Server ready July 12, 2018 10:58:40 AM PDT

I get the same message when trying to use Gmail SMTP servers or a different account. Can anybody help with this?

Using Windows 10, XAMPP, CodeIgniter 3.1.9.

好的，所以我通过添加以下行来解决此问题：

$this->email->set_newline("\r\n");
