各位大哥，突然间我的MDaemon邮箱就发不了外部邮件了，只能收取；内部间没问题。退信内容如下：


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.

看這一個訊息應該是DNS問題
由外部dns檢查你的dns外部是否可以正常查閱
www.zoneedit.com/lookup.html
再來
用你的dns去查詢對方mail 相關dns
是否正常
這樣應該就有解答了

更换DNS
