Email Applescript邮件标记在maverick中不起作用？

我正在编写applescript，但以下内容不起作用：

我已经将文件放在脚本文件夹中，创建了一个查找消息的规则，但脚本从未发生过

我试图标记，改变背景颜色，但没有用。规则测试已存在。 这里怎么了

代码：

using terms from application "Mail"
-- on perform mail action with messages selectedMessages
set today to current date
set deleteDate to today - (7 * days)

on perform mail action with messages selectedMessages for rule test

    tell application "Mail"

        repeat with eachMessage in selectedMessages
            -- repeat with a from 1 to 5
            --- Process the current message
            --  set background color of eachMessage to white
            --  if date received of eachMessage in selectedMessages is after deleteDate then
            set background color of eachMessage to white
            set flagged status to false
            --  end if

            --  display dialog theText
        end repeat
    end tell
end perform mail action with messages
end using terms from
