急求！申请tandon的时候发送推荐信之后状态显示是以下字母？？？

An attempt to deliver the email has been made by the system. (25900,39)

Although there is a delay in providing the delivery status of the email, this does not mean that the email was not sent. As soon as the delivery status becomes available, you will be able to check whether the email has been delivered successfully or not.
我该怎么办！！！？？？？

我也遇到了，推荐人收不到学校推荐信。。。。完全找不到
