 //SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don'thave access to that date_default_timezone_set('Etc/UTC');
       require 'PHPMailer-master/PHPMailerAutoload.php';
      //Create a new PHPMailer instance
     $mail = new PHPMailer;
    //Tell PHPMailer to use SMTP
    $mail->isSMTP();
   //Enable SMTP debugging // 0 = off (for production use)
    $mail->SMTPDebug = 0;
 //Ask for HTML-friendly debug output
  $mail->Debugoutput = 'html';
//Set the hostname of the mail server
  $mail->Host = 'smtp.gmail.com';
   //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
             $mail->Port = 465;
    //Set the encryption system to use - ssl (deprecated) or tls
       $mail->SMTPSecure = 'ssl';
   //Whether to use SMTP authentication
     $mail->SMTPAuth = true;
//Username to use for SMTP authentication - use full email address for gmail
      $mail->Username = "username@gmail.com";//"lino.cspace@gmail.com";
   //Password to use for SMTP authentication
    $mail->Password = "yourpassword";//"lino@123";
      //Set who the message is to be sent from
       $mail->setFrom('admin@gmail.com', 'Admin');
       $mail->addAddress($ToEmail);
      //Set the subject line
        $mail->Subject = 'Enquiry Mail';
       $mail->Body = $MESSAGE_BODY;//'this is test msg on 25-jun.';
       if(!$mail->Send()) {
         echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
           echo "Message sent!<br>";
          }
       }

Answer 1

Enable smtp debugging

$mail->SMTPDebug = 1;

OR

 $mail->SMTPDebug = 2;

Then the error info will give you more info on the error

if (!$mail->Send())
{
    echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
    echo "Message sent!<br>";
}
