SMTP + Gmail错误：邮件未发送

Question

I'm trying to send email. This is the code that I have written.

config['protocol']      = 'smtp';
$config['smtp_host']    = 'ssl://smtp.googlemail.com';
$config['smtp_port']    = '465';
$config['smtp_user']    = 'mymail@gmail.com';
$config['smtp_pass']    = '123';
$config['mailtype']     = 'html';
$config['charset']      = 'iso-8859-1';
$config['wordwrap']     = TRUE;    
$config['newline']      = "\r\n";

Here's the error i'm getting:

The following SMTP error was encountered: 110 Connection timed outUnable to send email using PHP SMTP. Your server might not be configured to send mail using this method.

The below configuration works perfectly for me even with Gmail.

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_port'] = 465;
$config['smtp_user'] = 'example@gmail.com';
$config['smtp_pass'] ='yourmailpassword';
$config['mailtype'] = 'html';

$this->load->library('email', $config);

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

$this->email->from('from@gmail.com', 'TEST MAIL');
$this->email->to($to);
$this->email->subject($subject);
$this->email->message($message);

$this->email->send();

Don't forget to enable less trusted app access in your Gmail account. I was able to send both simple text emails and emails with HTML templates and images with above configuration without any problem.
