You should use your email client's Reply feature to reply to one of the
existing messages in the thread.  This will put the right things in the
Subject:, To: etc. fields, and also include a hidden header field called
References: which refers to the post you're replying to.  Then when
someone receives your message, their email client will see the References:
header and know that your reply was part of the same thread as the message
to which you replied.
