    // Select an IMAP mailbox
    success = imap.SelectMailbox("Inbox.RubyMail");

    // individiually, but this is less efficient:

    int n = messageSet.get_Count();

        success = imap.SetFlag(messageSet.GetId(i),messageSet.get_HasUids(),"Deleted",1);

            System.out.println(imap.lastErrorText());
            return;
            }

        i = i+1;
        }

    // Expunge and close the mailbox.

    // Display the session log.

    // Disconnect from the IMAP server.
