請問一下,我mail server架好很久了,使用都很正常最近要寄信給這家客戶就都會被退信
退信內容如下:
452 4.2.1 Your host 211.21.xx.xx has no DNS record . If you are using a firewall please configure DNS and try again authoritative host not found: [email protected]

請各位大大幫小弟解釋這是出在那邊的問題....

能不能再完整一點？光是一行的 log，看不太出來問題在哪。

看起來是反查的問題。對方反查你的伺服器但查不到。
必須重你的 DNS 設定著手。如果是代管，向你的上層去設定反查。
反查的相關文件請利用右上角的小幫手搜尋，可以找到不少。
