小弟感覺應該是總公司DNS server無法解析對方domain name
小弟對MDaemon還很不熟= =
請問我該從哪裡去設置修改呢

只有特定的這間公司有問題？如果是，可能是對方的網域解析設定不正確。
不過看起來，你們自己的伺服器與外部 DNS  伺服器的通訊似乎也有問題。

是的 昨日又發生一次了
公司員工要寄信給大陸客戶

發生狀況是
1. 公司user說 他們收不到我們發的信，但我們並沒有被退信，2. 有時公司user也會收不到對方的信件
這問題會是我公司DNS問題  還是對方的DNS呢

MarchFun

這問題可能複雜了。如果是一律寄不出或收不到就好解決。但特定一間公司又是在大陸，或許牽涉到對岸防火長城從中搞鬼。
可以試著用其他的個人帳號 (非貴公伺) 進行測試。看對方收不收得到。

抱歉我沒敘述清楚

這一次是大陸的分公司的員工寄給大陸的客戶公司

只有這家會這樣，其餘寄送一切正常
