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. -- Richard Welty (welty@ge-crd.arpa) --------
