应该是说你是Open Relay服务器。

谢谢！
意思是说发信的服务器是Open Relay服务器吗？

我的问题和你的有点类似，发往美国的一个公司。发不出去，发出去也收不到。高手请看看。

传送失败报告
您的文件：
未送至:
因为： Error transferring to mail.BANNERENGINEERING.COM.CN; SMTP Protocol Returned a Permanent Error 553 Invalid sender: xxx@xxx.com.tw

您应该怎么做？
您可以选取「重送」按钮或「动作」菜单的「重送」指令，将未送达的文件重新给上面列出来的收件者。
当您重送文件后，您可以删除此送件失败报告。
如果无法重送文件，您会收到新的失败报告。
除非您收到其它送件失败报告，否则文件已经成功地送到所有其它的收件人。


大家能否也帮我看看以上.

重送估计是不行了 试试看 重新发送吧！

就是发邮件给对方时立即出现此退信 重来没重试过 但听user说发了有时又能收到 出现前天的邮件昨天收到 我这边也能正常解析那个地址.
