I don't keep up with all the "features" of all the mail systems, only the
ones that cause problems on my lists.  I've never encountered this.  What
is it, and how is it supposed to work?

As one really can't "unsend" what has been sent, especially once delivered,
any more than one can "unsay" what one has said and been heard by others,
what is this supposed to do?  Delete the item from the recipients email
inbox?  What if it has alrady been read?  Saved to some other file/folder?
