I received the mail continuously fine but suddenly I didn't receive any mail. I don't know what happened with my code also I didn't get any error in my error log file as well. I am using it on Godaddy server
$mails = new PHPMailer();
    $mail->IsSMTP();
    $mail->Host = "smtp.gmail.com";
    $mail->SMTPAuth = true;
    $mail->Port = 587;
    $mail->Username = "mymail@gmail.com";
    $mail->Password = "myPassword";
    $mail->From = "foo@gmail.com";
    $mail->FromName = "John Doe";
    $mail->AddAddress('foobar@foobar.com');
    $mail->IsHTML(true);
    $mail->Subject = "John Doe Lead Update";
    $mail->Body = '
        <h2>Mahindra Campaign Data</h2>';
        if($mail->send()){
            echo 'Message sent';
        }
           else
         {
            echo 'Mailer error' .$mail->ErrorInfo;
        }
