I don't see any reason to combine the list handler and the archive
handler in the same program at all. Why not make a generic
email to archive program, connect it to a separate alias and
subscribe the alias to the list? That way you can have the archive
on another machine or multiple copies in different locations and
sendmail does all the work for you. Or if you want to archive
someone else's list it all works the same.
