Codeigniter stopped sending mails from gmail smtp on wamp server windows 10 - smtp

Question

The code i am posting was working fine for 2 months. Now, from some reason it stopped sending mails.
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'ssl://smtp.googlemail.com',
'smtp_port' => 465,
'smtp_user' => 'system#gmail.com',
'smtp_pass' => 'xxxxxxx',
'mailtype' => 'html',
'charset' => 'iso-8859-1'
);
$this->load->library('email', $config);
//za da mi ispraka na sevisniot mail i da mozam da sledam dali ispraka izvestai dokolku oni stiklirale isprakanje
$this->email->clear(TRUE); //za reset pred sekoe novo prakanje od jamkata
$this->email->set_newline("\r\n");
$this->email->from('doNotReply', '');
$this->email->to('service#gmail.com');
$this->email->subject($subjectStart . ' izvestaj');
$this->email->message('');
$this->email->attach('D:/wamp64/www/dica/assets/iEksel/'. $filename);
if ( ! $this->email->send()){
$myfile = fopen("mail.txt", "a") or die("Unable to open file!");
$txt = $this->email->print_debugger();
fwrite($myfile, $txt);
fclose($myfile);
}
The debugger outputs this errors:
The following SMTP error was encountered: 0 Unable to send data: AUTH LOGINFailed to send AUTH LOGIN command. Error: Unable to send data: MAIL FROM:< doNotReply >< pre>from: The following SMTP error was encountered: < br />Unable to send data: RCPT TO:< br />< pre>to: < /pre>The following SMTP error was encountered: < br />Unable to send data: DATA< br />< pre >data: The following SMTP error was encountered: < br />Unable to send data: User-Agent: CodeIgniter.
Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.
Does anyone has an idea why this code that worked perfectly for 2 months, now fails to work?

Answer 1

You dont need this smtp code for server-side.
for server-side this much code is enough:
$this->load->library('email');
$config['mailtype'] = 'html';
$this->email->initialize($config);
$this->email->to($this->input->post('emailtxt'));
$this->email->cc($this->input->post('cctxt'));
$this->email->from($fromEmail['user_email']);
$this->email->subject($this->input->post('smailtxt'));
$this->email->message($this->input->post('tamailtxt'));
$this->email->attach($pathfile);
$this->email->send();
and for client side the code you used looks find. Issue must be if smtp user email and password is changed or check php.ini file in wamp.

Instead of smtp used smtps in array.
$config = Array(
'protocol' => 'smtps',
'smtp_host' => 'ssl://smtp.googlemail.com',
'smtp_port' => 465,
'smtp_user' => 'system#gmail.com',
'smtp_pass' => 'xxxxxxx',
'mailtype' => 'html',
'charset' => 'iso-8859-1'
);
