是我们服务器的问题还是SINA的问题？

Answer/Solution: This error indicates that the network connection between IMail and the remote server has been forcibly closed. This could be due to configuration at the remote server (although in these cases, an error is expected before rejecting a TCP connection) or due to network issues. In most cases, contacting the administrator of the remote system is advised before troubleshooting the network connection between your server and the remote SMTP server.

谢谢liujun1071

11：55发给SINA的还能收到，之后就又是上面的错误了；打给SINA，SINA说***@vip.sina.com这个邮箱是正常的。没办法，重启了自己的服务器就发出去了￣晕！<br>
怎么回事呢？当时只有发到SINA的出现了上面的错误，其它的都正常收发。大家再帮分析一下？
