<p>I'm subscribed to a blog post and receive lots of emails by users replying to that post. As those emails don't include an <code>In-Reply-To</code> header, my inbox fills up with pages and pages of messages, rather than producing a threaded view of all emails. Not sure if Rails suppors this at all, but it would be quite handy.</p>
