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?

你這個問題跟之前那個是差不多的，所以合併過來。其中的問題也是一樣，解析不到對方的 MX 記錄。

chiawei29

版大，請問一下，
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?

MarchFun

能能查到對方的MX記錄嗎？從你的 log 看起來都是查不到的。

chiawei29

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?

chiawei29

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?

MarchFun

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。

chiawei29

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>"<

MarchFun

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。

chiawei29

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>"<
15 second wait for DNS response exceeded (attempt 1 of 3).
MX-record resolution of [def.com.tr] in progress (DNS Server: 168.95.192.1)...

MarchFun

那麼你的 mail server ping 得到 168.95.192.1 嗎？

隨風浮雲

def.com.tr 這個位置，我也解析不到，真的有這個網址嗎?

chiawei29

隨風大，沒有此網址，這是我改過的

chiawei29

回覆 15# MarchFun
March大，我可以ping到

隨風浮雲

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。

chiawei29

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。
