Email sent but not received - codeigniter

Question

The result from email sending is true but email is not received. My configs looks like this:
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'smtp.gmail.com',
'smtp_port' => 587,
'smtp_user' => 'tomaivanovtomov#gmail.com',
'smtp_password' => 'abc9110033969qwe',
'mailtype' => 'html',
'charset' => 'iso-8859-1',
'smtp_timeout' => 10,
'smtp_crypto' => 'tls'
);
$this->load->library('email', $config);
If I try the other way with $this->email->initialize($config) and $this->load->library('email') before it, when try to send it I get an error:
fsockopen(): unable to connect to smtp.gmail.com:587 (Connection refused)

Answer 1

Try to modify the connection to use ssl instead of tls, and port 465 instead of 587 :
'smtp_port' => 465,
'smtp_crypto' => 'ssl'

Answer 2

Change smtp host with
'smtp_host' => 'ssl://smtp.gmail.com',
Check you smtp_port and provide correct your port number with
'smtp_port' => 587,
And change crypto type with ssl
'smtp_crypto' => 'ssl'

Answer 3

try to do it in following order.
$this->load->library('email');
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = 'abcdef#gmail.com'; //your email address
$config['smtp_pass'] = 'testingmails'; // password
$config['smtp_port'] = 465;
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;
$this->email->initialize($config);
