exchangr5.5 只能收,不能发,MTA服务自动停止.事件查看器有错误如下:'An error was returned from the messaging software the Internet Mail Service uses to process messages on the Microsoft Exchange Server. It is possible that the piece of mail being processed at the time will be returned to the sender as a failed delivery instead of being delivered. The message will be moved to the "BAD" folder, if possible, and the error is not a temporary error. Otherwise it will be retried when the service is restarted. Use the appropriate utilities found in the SUPPORT directory of your Exchange CD to view and manipulate messages that have been moved to the "BAD" folder.'请各位帮忙看一看
