可以寄信卻不能收信的問題...
本文章最後由 penuins 於 2009-1-15 08:16 AM 編輯各位大家好
公司用的環境是Server 2003，MDaemon 的版本是9.5.2
最近公司同仁反應寄信給某一廠商，該廠商可以收到我們寄出去的信
但當該廠商寄信給我們時卻被退信了 (是直接對我們寄去的信點回覆，所以沒有位址打錯的問題)
而且廠商還有多寄一份副本到Yahoo的信箱，Yahoo的卻有收到
以下是廠商收到的退信訊息
There was a SMTP communication problem with the recipient's email server.Please contact your system administrator.

痲煩大家幫忙了
謝謝 Tue 2009-01-06 07:44:16: --> 550 192.156.198.16 does not pass SPF requirements for domain
看這句，對方未通過 SPF 的檢查。
目前設置 SPF 的人不多，建議你可以勾選要檢查，但不要設定檢查不過就拒收。 您好，剛剛去Server看過了
SPF已經是設定成要檢查，檢查不過也照送
也有將對方列入白名單了…
可是還是有收不到的問題… 至少這個 LOG 看來是因為 SPF 的原因。其他收不到的問題還得看當時的 LOG 才知。 本文章最後由 penuins 於 2009-1-15 03:33 PM 編輯
您好，我們剛剛又請對方寄了一次測試信
一樣是收不到，也是出現does not pass SPF requirements for domain
目前除了將SPF設定成要檢查，檢查不過也照送之外
也將其他比對積分的機制都關掉了
麻煩您協助了 謝謝
<刪略> 那些 abc, xyz 等字樣是有改過的？應該不是真的是這樣吧？ 本文章最後由 penuins 於 2009-1-15 04:28 PM 編輯
不好意思...
我重貼一次LOG
<刪略> 把有關 SPF 的設定全部關掉再試試。 您好，昨天就已經先把Spam Filtering這邊是設定為flag the message but let it continue down the delivery path、Heuristics、Bayesian這兩個標籤頁下所有的勾勾都取消，才又連絡廠商寄測試信的，結果還是沒有收到...orz 你們有開啟反查 (Reverse Lookups) 嗎？有的話也關掉再試。 本文章最後由 penuins 於 2009-1-15 04:28 PM 編輯
把反查跟SPF全部關掉以後還是不行...
LOG如下
<刪略> 你們的伺服器真的有問題，因為再怎麼看，它還是有執行 SPF 的檢查。你可能要朝為何 SPF 的檢查關不掉這方面著手。 嗯，我再試試~
謝謝囉~
