Answer 1

In my setup I also have this:
$mail->SMTPSecure = "ssl";
$mail->Port = 465;
Note that you will probably need to authorise this action on your account. You'll get an email from gmail with a link.

This the answer for my post. Please see the link. Download PHPMailer_5.2.0.zip and unzip. I am using xampp server and I created folder in D:\xampp\htdocs\ with name phpMail. I copied these two files(class.phpmailer.phpclass.smtp.php ) from PHPMailer_5.2.0 to phpMail. Now make file sendMail.php and paste following code.
<?php
require("class.PHPMailer.php");
$mail = new PHPMailer();
$mail->SMTPSecure = "ssl";
$mail->Port = 465;
$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "smtp.gmail.com"; // specify main and backup server
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = "yourEmailAddress#gmail.com"; // SMTP username, sender email address
$mail->Password = "yourGmailPassword"; // SMTP password
$mail->From = "yourEmailAddress#gmail.com";
$mail->FromName = "YourName";
$mail->AddAddress("Receiver#gmail.com"); // Write the email of receiver. Who will get the mail.
$mail->WordWrap = 50; // set word wrap to 50 characters
$mail->IsHTML(true); // set email format to HTML
$mail->Subject = "Here is the subject";
$mail->Body = "This is the HTML message body <b>in bold!</b>";
$mail->AltBody = "This is the body in plain text for non-HTML mail clients";
if(!$mail->Send())
{
echo "Message could not be sent. <p>";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}
echo "Message has been sent";
?>
After writing the code your have to run server. In My case It was http://localhost/phpMail/sendMail.php. When You run this code from browser the you will get one mail regarding this app like Google Account: access for less secure apps has been enabled. When you click this link they asked for permission, Access for less secure apps click yes if you want. Thanks to #rjdown for help.
