Mail systems that allow unposting exist -- I have used one of them
fairly extensively.  The added complexity is enormous -- it always seemed
to me to be more complex than the added features justified.  The problem
is that the system must own the mailboxes of unread mail, and the
mail program must accordingly be more complex and have significant
privileges.  It always seemed a little dangerous to me ... also, the
user generally can't write his own mail reader very easily (if at all).
The unix-style mail does have its problems, but the alternatives are worse
in my book.
