I know, but for some reason whatever email client some people are using,
they aren't changing the in-reply-to header correctly. Thunderbird takes
an intelligent guess at how to thread it, by using the email subject.
What is even more annoying is when people hit reply to an existing
email, and start a completely new discussion (and it is then threaded in
reply to an existing topic). I can't win, can I? :)
