從上面這段可以看出解析不到對方的郵件主機，所以嘗試以對方的 A 記錄來當作是郵件主機來寄，但還是不成功。
寄給 def.com.mx 的信最後變成由 vps.chekkos.com 在處理。可以合理的懷疑是 def.com.mx 可能沒有設定 MX 記錄。
再一個猜測，def.com.mx 可能是由 vps.chekkos.com 託管。 感謝版大的回覆，以你的分析看來，代表原因發生在客戶端的設定是吧? 感謝版大的回覆，以你的分析看來，代表原因發生在客戶端的設定是吧?

應該是這樣沒錯！
寄給國外客戶時，會被退信
各位大大好，最近發生寄給某些客戶時，會被退信的情況，不知是何種原因導致的?已將資料更改如下：

最近這二個問題，都能查到對方的MX記錄，
但去PING此MX時，都timeout，
像這樣的情況下，是不是代表有可能是因為跨國連線時，封包有可能遺失導致的呢?
像ping 不到mx，也代表信件無法送達至對方的mail server吧? 能能查到對方的MX記錄嗎？從你的 log 看起來都是查不到的。
PING不到客戶的MX記錄
有一家客戶，我們一直沒辦法寄信給他們，我查得到他的MX記錄，但他們關閉PING的服務，所以導致PING不到此MX，
像這樣的例子，該怎麼解決呢? march大您好：
我用nslookup有有辦法查到對方的mx記錄，但ping不到，
像這樣情況，有辦法解決嗎? ping 不到的原因很難猜，但 MX 無法解析的問題多半是出在對方身上。可能得連絡對方請他們去查查看架設的 mail 主機有什麼方面的問題。 我nslookup 去查mx，如果有顯示資料的話，是不是代表mx沒問題呢?
我已有和對方連絡過了，但他覺得是我們自已server設定的問題>"< nslookup 查到的是登記在 DNS Server 中的相關資訊。查得到不代表沒有問題。你可以試試看用 Gmail 或其他的信箱寄信給他們，看寄不寄得到。 可以用gmail寄給這個帳戶。
現在路續有發生二、三個客戶，會發生以下退信的訊息，該不會真的是我的server設定有問題呢?
請March大幫幫忙>"<

MX-record resolution of in progress (DNS Server: 168.95.192.1)... 那麼你的 mail server ping 得到 168.95.192.1 嗎？ def.com.tr 這個位置，我也解析不到，真的有這個網址嗎? 隨風大，沒有此網址，這是我改過的 回覆 15# MarchFun
March大，我可以ping到 如果你可以直接PING 的到對方網址，那就自行 TELNET 他們的PORT試試，
看是那一段被踢的。 回覆 19# 隨風浮雲
隨風大您好：
對方都把ping的服務關閉，
您提到的"自行tlnet他們的port試試，看是那一段被踢的"這個部份該怎麼做呢?
再次感謝您的指導。
