求助：Mdaemon 发送邮件问题！

cohn

各位大侠，小弟用mdaemon 8.03作mail服务器，一直运行良好，不过最近两天发信突然有问题，给域内的用户发没有问题，可是给域外的用户发总是发不出去，（而且邮件会在remote queue持续好长时间）退信信息如下：<br>
The attached message had transient non-fatal delivery errors<br>
<br>
THIS IS A WARNING MESSAGE ONLY - YOU DO NOT NEED TO RESEND YOUR MESSAGE!<br>
<br>
This server is configured to automatically retry delivery at configured<br>
intervals. Subsequent attempts to deliver this message are pending.<br>
<br>
Failed address: xxx@hotmail.com<br>

你的DNS有问题<br>
The name server refuses to honor queries from this location

你邮件服务器使用的DNS服务器拒绝查询MX记录和A记录，你需要更换你的邮件服务器使用的DNS服务器。
