title: PHP Mail Don't Show "To" in "To" Header
body: <p>I want to make an email forwarder similar to cPanel's, where I have a database of email addresses, and where they should forward to, and I set a catch-all to pipe to my script.</p>
  
  <p>I have completed this script, however, I would like to make the "To:" field in the header show the address it was sent to, rather than who is was being delivered to. For example, the email was sent to user001@mydomain.com, and the script forwards it to me@gmail.com. How can I make PHP send mail to me@gmail.com, but still show user001@mydomain.com in the headers, like cPanel does?</p>
