body: <p>What's the difference between an email Sender, From and Return-Path value?</p>
  
  <p><strong>Example</strong>: I have a contact form where the user can input their email, would this be assigned to sender, from or return-path?</p>
  
  <p>I had a quick search on the StackOverflow and couldn't find anything useful.</p>
