PHPMailer - Mail not accepted from server Error - php

Question

I searched web for this issue but none of them solve my problem. I am trying to send single mail using PHPMailer. But I am getting this error in my browser screen.
SMTP -> FROM SERVER:
SMTP -> ERROR: RSET failed:
SMTP -> FROM SERVER:
SMTP -> ERROR: MAIL not accepted from server:
The following From address failed: mymailid#gmail.com : MAIL not accepted from server,,
SMTP server error:
Mailer Error: The following From address failed: mymailid#gmail.com : MAIL not accepted from server
My code to send mail is.
<?php
require_once('mailer/class.phpmailer.php');
date_default_timezone_set('Asia/Kolkata');
$to = $_POST['to'];
$subject = $_POST['subject'];
$msg = $_POST['msg'];
$mail = new PHPMailer();
$mail -> SMTPDebug = 2;
$mail -> IsSMTP();
$mail -> SMTPSecure = 'tls';
$mail -> Host = 'smtp.gmail.com';
$mail -> Port = 587;
$mail -> SMTPAuth = true;
$mail -> Username = 'mymailid#gmail.com';
$mail -> Password = '*********';
$mail -> setFrom("mymailid#gmail.com","Name");
$mail -> addReplyTo("mymailid#gmail.com","Name");
$mail -> Subject = $subject;
$mail -> msgHTML($msg);
$mail -> addAddress($to);
if(!$mail -> send()) {
echo "<h3>Mailer Error: ". $mail-> ErrorInfo . "</h3>";
}
else {
echo "<h1>Email Sent Successfully.</h1>";
}
?>
Please help me to solve this problem. Thanks in advance.

Gmail didn't accept your email and password as correct. You should use real credentials to authentificate or they will block it
