Solution 1

Are you try this?

$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'ssl://smtp.googlemail.com',
'smtp_port' => 465,
'smtp_user' => 'xxx',
'smtp_pass' => 'xxx',
'mailtype'  => 'html', 
'charset'   => 'iso-8859-1'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");

// Set to, from, message, etc.

$result = $this->email->send();

And make sure you had setting your email account with Allowing less secure apps to access your account

Quỳnh Nguyễn's answer worked for me too. However I think it's worth pointing out that my code fails unless I put the line

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

Without that line, gmail complaints about wrong user/password :|
