title: Emails, a different 'reply to' address than sender address
body: <p>I have a <code>contact form</code> on a website (a general form: <em>name</em>, <em>email</em>, <em>subject</em>, <em>message</em>) in which mails are sent using <em>google apps</em> smtp to the admins.<br>
  Currently if an administrator wants to reply to the mail directly selecting the reply option, the person's reply's <em>To</em> field will be filled by the sender's address automatically.   </p>
  
  <p>What I wan't to ask is, <strong>Is there any standardized way to pass on some additional info with the mail which would define any reply to the mail should go to this address instead of the sender's?</strong>  </p>
  
  <p>It does seems that there is a little chance for this option as it may lead to some problems due to spammers (They may define a custom reply field in their mail and a general user might not look where they are replying).  </p>
  
  <p>So as an alternative what I thought is to find a way to create a filter with sender's account which figures out the reply email address from the format and forwards the mail (Doesn't seems like a good solution and I have no idea how to achieve this).</p>
  
  <p>I have tagged django, though this is not directly related with this, as I will finally implement this through django. </p>
