仍然未能解決重複接信問題, 已將smtp log 看了一片, 不知為何會有重複的recipient, 請問有什麼情況才會出現此問題, thanks.
 
以下是smtp log的部份資料

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...<IMG alt="<img" src="http://www.suma.tw/forum/images/smilies/default/sweat.gif" border=0 smilieid="10"> 這麼多可能會讓人不想看下去，把重點的地方貼上來就好。

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: 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 發表於 2007-9-19 17:10:14

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 發表於 2007-9-19 22:29:18

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 發表於 2007-9-20 13:32:51

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 發表於 2007-9-20 13:58:37

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。

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^_^

TTL會影響的層面滿大
下次會多注意一點

明白了~~~~~~~~~~~~~~^_^
