PHPMailer - gmail smtp not working properly

Question

I use gmail smtp for contact form in my site.(PHPMailer script https://github.com/PHPMailer/PHPMailer‎)
my code is:

<?php
include "classes/class.phpmailer.php"; // include the class name
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587
$mail->IsHTML(true);
$mail->Username = "[email protected]";
$mail->Password = "xxxxxxxxxx";
$mail->SetFrom("[email protected]");
$mail->addReplyTo("[email protected]");
$mail->Subject = "Your Gmail SMTP Mail";
$mail->Body = "Hi, your first SMTP mail via gmail server has been received.";
$mail->AddAddress("[email protected]");
 if(!$mail->Send()){
  echo "Mailer Error: " . $mail->ErrorInfo;
}
else{
    echo "Message has been sent";
}
?>

It works but i have two problems:

1. I set $mail->SetFrom("[email protected]");
   but in my gmail show from: [email protected]
   

2. I set $mail->addReplyTo("[email protected]");
   but in my gmail when i click replay button email replayed to [email protected]

Answer 1

I found my answer. in your Gmail go to

setting ->accounts ->Send mail as

click Add another email address you own in new window enter new email address (example if your gmail is [email protected] you must enter [email protected])or(if your gmail address have dot you must change position of dot. example if your gmail is [email protected] you must enter [email protected])
don't forget uncheck Treat as an alias.
click next step.

go back to setting ->accounts ->Send mail as
make a new email as defult
check Reply from the same address the message was sent to
all done!
i change code use new codes.

now show from my site

now when you click replay botton show replay to user email

<?php
include "classes/class.phpmailer.php"; // include the class name
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; // or 587
$mail->IsHTML(true);
$mail->Username = "[email protected]"; 
$mail->Password = "xxxxxxxxx";
$mail->addReplyTo("[email protected]","user");
$mail->SetFrom("[email protected]","My Site");
$mail->Subject = "Your Gmail SMTP Mail";
$mail->Body = "Hi, your first SMTP mail via gmail server has been received.";
$mail->AddAddress("[email protected]");
 if(!$mail->Send()){
  echo "Mailer Error: " . $mail->ErrorInfo;
