以上有四篇一大堆的 log 內容已經刪除...

請將 log 精簡一下再貼吧... 這麼多可能會讓人不想看下去，把重點的地方貼上來就好。

snke

對不起, 重點大概在這裏, TO的時候, 不知為何做了重複的動作, 這個是smtp log的, 在dpop log也發現此問題, 會否是address alias所導致?

看看這句：

 

Tue 2007-09-18 09:36:11: [596:7699] 250 RSET? Well, ok.

 

這表示在傳送過程中，信送到一半對方就「打退堂鼓」然後又重來一次，所以你會收到重覆的內容。至於為何送一半會中斷，雙方之一的郵件伺服器的設定一定有個癥結存在。或許跟 TTL 之類的逾時值有關。

snke

謝回覆, 但是寄件者和收件者也是相同域名的, 所以傳送過程問題應多數會在那裏發生? TTL的逾時值在那裏可調教?

MarchFun

如果同網域也這樣，或許問題就不在 TTL 上面。這個就要你自己去找出為何傳輸會中斷重來的原因了。因為你們那邊的狀況對我來說是瞎子摸象啦！

 

建議把一些過濾郵件的機制全部關閉，讓它處於最單純的狀態以減少需要考慮的因素，然後再去查。

snke

原來過濾郵件機制都有關係架...@@"", 我set了很多條rule呢..., 我試下減除一些rule先.. 但是有點不明白, 過濾機制不是當某條件成立後就行事嗎? 我全部rule都是指哂向1bad quene的

MarchFun

我指的不是只有 Content Filter 這個過濾，是所有的 Security 中的所有機制。全部關掉後再慢慢查。

snke

security中設定了以下勾選, 我試試關閉了來測試一下

張貼上來讓自己記下改動了那裏...^^"

(sry...又用了快速回覆mode...@@)

 

SMTP Authentication

- Authenticated senders are valid regardless of the IP they are using

- Authenticated users are exempt from the POP Before SMTP requirement

 

Spam Blocker Engine

- Enable Spam Blocker engine

- Always exempt Trusted IPs from Spam Blocker lookups

 

Mail relaying

- This server does not relay mail for foreign domains

- Refuse to accept mail for nonexistent local users

 

Reverse lookups

- Refuse to accept mail if a lookup returns 'domain not found'

- Send 501 error code (normally sends 451 error code)

- Insert 'X-Lookup-Warning' header into suspicions messages

snke

匯報進度先~轉了setting後, 問題好像沒有再出現了~~~相信的確是security中出現問題...但是那裏出現問題就要再測試了.

 

多謝MarchFun給我的意見^_^

monderhome

TTL會影響的層面滿大 下次會多注意一點

snke

明白了~~~~~~~~~~~~~~^_^
