關於新mail server問題

s87080400

各位前輩好
小弟近期幫公司架設一台新的mail server (MDaemon目前完全都是預設選項)
卻發生一個問題 無法寄信給公司舊的mail server會被退信
但是寄給google yahoo等等各大網站信箱都沒問題  
小弟新的mail server是連接到新架設的AD網域控制站 內部DNS位址是192.168.1.5
新的mail sever 位址 192.168.1.4
現在情況是不管我用內部外部DNS 新的mail server都無法寄信給舊mail server，
但是如果從舊的mail server寄給新的mail server是可以通的
以下是我的錯誤log 假設舊公司mail server domain是 p2p.com
