Option to Manage messages by Senders = 1) Every message from a Selected Sender gets sent to a Selected Folder 2) Then the Messages from the Selected Sender can be, OPTIONALLY, be PURGED to some desired Number of Copies,
EX: Message M(T) from S gets sent to Folder F & marked as read; then ONLY the Last 2(Number of Copies to keep) are kept [M(T) to M(T to NC-1) allows messages to actually be read later].
