Send e-mail with Codeigniter 3.0.3 via SMTP

Question

My email.php located within config/ folder:

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'smtp.gmail.com';
$config['smtp_port'] = '465';
$config['smtp_user'] = 'gmfernandes@[domain].com';
$config['smtp_pass'] = '[password]';
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['wordwrap'] = TRUE;
$config['newline'] = "\r\n";

My email() method:

public function email()
{
    $from_name = $this->input->post('nome_email');
    $from_email = $this->input->post('email_email');
    $to = 'gmfernandes@[domain].com';
    $subject = 'Testing';
    $message = $this->input->post('proposta_email');

    $this->email->from($from_email, $from_name);
    $this->email->to($to);
    $this->email->subject($subject);
    $this->email->message($message);

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

    die;
}

My autoload.php:

$autoload['libraries'] = array('database', 'session', 'form_validation', 'email');

I am trying to make this work. I have spent hours looking for a solution but NONE of them helped me. Removed and installed sendmail and postfix several times, tried to use default configuration but nothing. It doesn't work with me.

Now, the message that is shown:

hello: F

Edit #1

After chaning my config.php file to ssl://smtp.gmail.com, a new and bigger error message has shown. Above the User Agent: CodeIgniter:

Answer 1

You use the port 465, which means SSL.

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

Answer 2

function Email()
{
        parent::Controller();   
            $this->load->library('email');
}

function index()
{
    $config['protocol']    = 'smtp';
    $config['smtp_host']    = 'ssl://smtp.gmail.com';
    $config['smtp_port']    = '465';
    $config['smtp_timeout'] = '7';
    $config['smtp_user']    = 'mygmail@gmail.com';
    $config['smtp_pass']    = '*******';
    $config['charset']    = 'utf-8';
    $config['newline']    = "\r\n";
    $config['mailtype'] = 'text'; // or html
    $config['validation'] = TRUE; // bool whether to validate email or not      

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


    $this->email->from('mygmail@gmail.com', 'myname');
    $this->email->to('target@gmail.com'); 

    $this->email->subject('Email Test');
    $this->email->message('Testing the email class.');  

    $this->email->send();

    echo $this->email->print_debugger();

     $this->load->view('email_view');

   }

Answer 3

Done. It worked. I had to allow access from less secure apps in My Account > Sign-in & security configurations and do as Schellingerht said.

Answer 4

Try with ssl://smtp.googlemail.com instead of smtp.gmail.com

$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->from('your@example.com', 'Your Name');
$this->email->to('someone@example.com');

$this->email->subject('Email Test');
$this->email->message('Testing the email class.');

$this->email->send();
