title: Setting different reply-to message in Python email/smtplib
body: <p>I am using Python email and smtplib to send an email from Python. I am doing this via the Gmail SMTP server using my Gmail credentials. This works fine, however I would like to specify a <code>Reply-to</code> email address different from the <code>from</code> address, so that replies go to a separate address (non-Gmail.)</p>
  <p>I have tried creating a <code>reply to</code> parameter like this:</p>
  <pre><code>   msg = MIMEMultipart()
  
     msg['From'] = &quot;email@gmail.com&quot;
     msg['To'] = to
     msg['Subject'] = subject
     msg['Reply-to'] = &quot;email2@example.com&quot;
  </code></pre>
  <p>But this doesn't work. Can't find any info on this in the Python docs.</p>
