title: imaplib for retrieving replies to an email
body: <p>I'm using <code>smtplib</code> in python to send emails. I want to fetch any replies to these emails.
  Does <code>imaplib</code>provide option to search inbox emails using message id of the parent email?
  I'm sure it does because that's how email clients like outlook etc. get it done.</p>
  <p>I want to do something like the code below -</p>
  <pre><code>result, data = mail.fetch(None, f'(PARENT-MESSAGE-ID &quot;{parent_msg_id}&quot;)')
  </code></pre>
  <p>How can I achieve this?</p>
