Typically, threading is handled by the MUA, and relies on the
Reply-To and In-Reply-To headers. Some mail readers (mutt for example) do
add additional granularity if the Reply-To/In-Reply-To headers match, but
subject differs, but subject is definately not the mechanism used to
determine threading.
Since you're using Yahoo's webmail client, you may want to build an
address book and use that to create addresses, or use some templates.
Perhaps keep a "dummy" message to the list in your drafts folder, and always
"reply" to that one?
