Sending SMTP email from PHP Script hosted on Hostgator Servers

Question

I have created a web application as such in the application I require to send to send users their passwords if they have forgotten them. Now I use a gmail account to send the email. When I send the email locally from my machine using XAMPP everything works fine and it delivers as expected. When I look to put the php script onto a Hostgator server and try send the user their password I can't. But the reason I think this is happening is because Gmail immediately send me the following:

Someone recently used your password to try to sign in to your Google Account [email protected]. This person was using an application such as an email client or mobile device. 

We prevented the sign-in attempt in case this was a hijacker trying to access your account. Please review the details of the sign-in attempt:

IP Address: 198.57.247.245 (gator3281.hostgator.com.) 
Location: Los Angeles, CA, USA


If you do not recognize this sign-in attempt, someone else might be trying to access your account. You should sign in to your account and reset your password immediately

Based on this email I would assume that Gmail is touchy that hostgator is trying to send an email via them. My problem is I don't know how to fix this problem (This is my first time doing something like this) As such I was using a PHP framework called codeigniter and here is the code used to send the email (Note this code works more than fine locally i.e. I dont think there is anything wrong with the code):

public function SendEmailValidate($email,$subject,$message,$type)
    {
        $config = array(
                        'protocol' => 'smtp',
                        'smtp_host' => 'ssl://smtp.googlemail.com',
                        'smtp_port' => 465,
                        'smtp_user' => '[email protected]',
                        'smtp_pass' => 'mypassword',
                        'smtp_timeout' => 30,
                        'mailtype' => $type
                        );
        $CI = &get_instance();

        $CI->load->library('email',$config);
        $CI->email->set_newline("\r\n");
        $CI->email->from('[email protected]','Book Bay');
        $CI->email->to($email);
        $CI->email->subject($subject);
        $CI->email->message($message);

        if($CI->email->send())
        {
            return true;
        }
        else
        {
            return false;
        }
    }

Any help on this matter would really help, thanks

Answer 1

its in your gmail settings; you need to allow your website to send emails;

to do so go to https://accounts.google.com/DisplayUnlockCaptcha and click continue; then useyour website to send email an email; and google will detect your login attempt and allow you.
