title: To where goes bounce mails, From or Reply-to
body: <p>We are having a system that sends mail on behalf of the user (the user provide his own mail address).</p>
  
  <p>The mails are send via our server and are set up to with our company mail address as <code>From</code> (as many of our clients have disallowed third party to send mails withe their address as <code>From</code>) and with the users mail address in the <code>Reply-to</code>. </p>
  
  <p>Is it true that bounce mails are going to the <code>Reply-to</code> address rather than to the "From" address.</p>
