新架设的MDEMON邮箱无法发送到外网邮箱

zjsxlitc

无法发送到外网邮箱，但是本邮箱内可以互发。我是用FOXMAIL客户端发送的，如果用WEB方式发送，则提示有错误，根本无法发送。发送不出去的邮件MDAEMON自动回复给我，提示信息如下：

The attached message had transient non-fatal delivery errors
THIS IS A WARNING MESSAGE ONLY - YOU DO NOT NEED TO RESEND YOUR MESSAGE!
This server is configured to automatically retry delivery at configured
intervals.  Subsequent attempts to deliver this message are pending.
Failed address: zjsxlitc@126.com

=====================================
我查看了MDAEMON，所有发往外网的邮箱，都在REMOTE QUEUE和 RETRY QUEUE里了。按PROGRESS NOW 无反应。

请问是什么原因？
