Question

etting fsockopen(): unable to connect to ssl://smtp.gmail.com:465 (Connection refused) while sending email.

My email Controller is :

public function send() { 
     $from = "abc@gmail.com"; 
     $to = $this->input->post('email'); 
     date_default_timezone_set("Asia/Kolkata");

     $ci = get_instance();
        $ci->load->library('email');
        $config['protocol'] = "smtp";
        $config['smtp_host'] = "ssl://smtp.gmail.com";
        $config['smtp_port'] = "465";
        $config['smtp_user'] = "abc@gmail.com"; 
        $config['smtp_pass'] = "Mypwd";
        $config['mailpath'] = "/usr/sbin/sendmail";
        $config['mailtype'] = "text";
        $config['newline'] = "\r\n";

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

     $this->email->from($from, 'Your Name'); 
     $this->email->to($to);
     $this->email->subject('Email Test'); 
     $this->email->message('Testing the email class.'); 

     //Send mail 
     if($this->email->send()) {

     $this->load->view('pages/successfully'); }
     else {

    echo "Error in sending Email.";
      show_error($this->email->print_debugger());
     }
  }

Answer 1

Connection refused means exactly that the connection to the peer was refused. This is because the server either does not expect connections at the port or because a firewall is blocking the connection. It is probably the last one in your case so check for firewalls which might block the access on the local machine but also in the network. It might also that a firewall in front of the server or the server itself is blocking access for example if your system is on some blacklist known for sending spam.
