smtp - Sending mail from localhost using PHP

Question

I am trying to send mail from localhost using PHP. I am using the following code to send the mail :-

<?php
$to      = 'o****e@gmail.com';
$subject = 'hey You';
$message = 'Can you identify me :P';
$headers = 'From: at*****t@gmail.com' . "
" .
    'Reply-To: at*****t@gmail.com' . "
" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>

At first, I tried to send the mail to myself(at*****t@gmail.com), it worked fine. However, after that, now if I am changing the $to, its still sending the mail to same ID(mine) with the previous contents(not the updated one).

Is my request getting cached somehow ? Why every mail is being repeatedly sent to me irrespective of change in both contents and $to ?

1. Go to your php.ini file and change SMTP = localhost to SMTP = aspmx.l.google.com and uncomment sendmail_from and put in your sending gmail address. and set smtp_port = 25

2. Restart localhost
