發生了電郵錯派的情況

CPT

由[email protected]的電郵是寄給 [email protected] 和 [email protected] 的。SMTP (IN) 和 ROUTING LOG 也證實了這一點。

SMTP (IN) Log shows there was a mail incoming from [email protected]

但最終只有 [email protected] 收到而 [email protected] 收不到。其怪的是分公司的第三者收到了同一個電郵，證據如下：

看得眼花了，你們公司內部有幾個網域？除了 b.com.hk 之外， pc.com.hk 是否也是你們的？那個 mail.b.com.hk 又是哪來的？

CPT

我們公司的網域是 b.com.hk，而姊公司pc.com.hk 在我們同一個單位內但有另一個網絡，我們網絡之間有互信的關係，所以是相通的。但姊公司的MDaemon是分開的。

簡單說句，有外來的電郵給我公司，但錯派了給姊公司的另一人。而這情況出現了幾次，不同的外來寄件人，但總是錯寄了給姊公司的同一個人。

CPT

有其他人遇到這個情況嗎？可否提供一些意見？謝謝。

MarchFun

姊公司pc.com.hk 有自己的 MDaemon，正常來說不可能會把寄到 姊公司pc.com.hk 的信變成寄到  b.com.hk。所以可以猜測，問題大半是出在 DNS 的對應上。請 姊公司pc.com.hk 檢查一下他們的 DNS 伺服器的設定。

CPT

謝謝回覆，其實事情的發生應該是寄到我們公司 b.com.hk 的電郵，只有 "Bcc" 能成功到達 user2 的手上，而"To" 則被轉到姊公司 pc.com.hk。

但看了一下我們的 DNS 並沒有什麼不對的設定。請問還有什麼我可以嘗試？

MarchFun

檢查一下別名 (Aliase) 的地方有沒有什麼問題。

CPT

可否再詳述我應該找些什麼嗎？

MarchFun

請姊公司也查一下他們的 DNS 設定是否有問題。尤其是在 MX 記錄這方面。

CPT

在我公司的MDAEMON裡有一個ALIAS的設定：

postmaster@*[email protected].

是這設定有問題嗎？

MarchFun

這個設定沒有問題，問題極可能是你們姊公司的 DNS 設定。

CPT

請問我應該要姊公司找些什麼的DNS錯誤？

CPT

剛剛問了姊公司的 Admin, 他們使用的DNS與我公司用的都不一樣。我還可以從何入手？

MarchFun

不太了解你的意恩，他們的 DNS 設定當然不會跟你們的一樣阿！
如果這個問題只出現過一次，那就把它當作是偶發的吧！

CPT

已經向姊公司了解過，他們的DNS設定沒有問題，而他們的電郵也收發正常。

因為這個情況在過去兩個月已經出現了三次，所以想請大家幫忙。

MarchFun

請將姊公司的 DNS 設定內容提供來看看。
