Answer 1

Google has gone on to reject sending emails using an unauthorized application.

If you take a look at your Gmail inbox, you will get a Google email stating that a login tactic has been blocked.

https://support.google.com/a/answer/176600?hl=pt-BR

From the link above:

"You need to set up an SPF record for the domain with the address device or application IP in order to ensure that the recipients do not reject emails sent by that address. You also need to add this IP address to the Mailing List box authorized in the Google Admin Console. For example, if the sending device for 123.45.67.89, add this address to SPF registry without removing Google Apps email servers from record: v=spf1 ip4:123.45.67.89 include:_Spf.google.com ~all"

UPDATE: You can even use your gmail for sending, but you can’t use your own domain as a FROM email, so you need to enable the use of less secure applications at this link and change your code:

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

Answer 2

Friend, your gmail host settings are incorrect. Follow the correct setup, try this one.

$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);
