關於「X-Return-Path」

有廠商反應說：由我公司寄過去的信，都會被當作廣告信，但如果是回信的就正常
他們檢查後發現是我公司寄信時的寄件人會出現異常
我檢查後發現一個現象，舉例會變成如下：
from: <A href="mailto:[email protected]">SpamMail<A href="mailto:[email protected]">@instant.com.tw</A></A>
X-Return-Path: <A href="mailto:[email protected]">prvs=1901a27026=<A href="mailto:[email protected]">SpamMail<A href="mailto:[email protected]">@instant.com.tw</A></A>
</A>

我目前檢查的結果發現在我安裝 9.6.3  之後的信都會這樣
但我使用的上一個版本 9.5.6 就不會.....無解的話，那我只能回去使用 9.5.6 了
 
這是我收到信得檔頭部份： Return-path: <<A href="mailto:[email protected]">[email protected]</A>> Received: from by instant.com.tw (instant.com.tw) (MDaemon PRO v9.6.3) with ESMTP id md50000146118.msg for <<A href="mailto:[email protected]">[email protected]</A>>; Wed, 16 Jan 2008 13:28:36 +0800 Date: Wed, 16 Jan 2008 13:28:41 +0800 From: <<A href="mailto:[email protected]">[email protected]</A>> To: <A href="mailto:[email protected]">[email protected]</A> Subject: test Reply-To: <A href="mailto:[email protected]">[email protected]</A> Message-Id: <<A href="mailto:[email protected]">[email protected]</A>> MIME-Version: 1.0 Content-Type: text/plain; charset="BIG5" Content-Transfer-Encoding: 8bit X-Mailer: Becky! ver. 2.44 X-Spam-Processed: instant.com.tw, Wed, 16 Jan 2008 13:28:36 +0800 (not processed: message from trusted or authenticated source) X-Rcpt-To: <A href="mailto:[email protected]">[email protected]</A> X-MDRcpt-To: <A href="mailto:[email protected]">[email protected]</A> X-Return-Path: <A href="mailto:[email protected]">prvs=1901a27026=[email protected]</A> X-Envelope-From: <A href="mailto:[email protected]">[email protected]</A> X-MDaemon-Deliver-To: <A href="mailto:[email protected]">[email protected]</A> X-Antivirus: AVG for E-mail 7.5.503

我們這裏寄出去的信也是會有prvs=1901a27026 這類的內容，但寄出的信還沒發現什麼問題。

jtain 發表於 2008-1-17 18:27:24

底下是廠商的信 
 
由於貴公司發過來的信都一直被檔在垃圾信件
造成xx無法在第一時間收到您的訊息
xx向MIS部門確認後
發現在貴公司的email前面都會有一堆英數字
才被我們系統認為是垃圾信
麻煩幫忙詢問貴公司MIS部門一起解決這個問題吧

這是 MDaemon 最新的 Backscatter Protection 防護技術（ BATV 回信驗證），相關的文件你可以參考：

你可以試著將 Backscatter Protection 功能關閉看看。

啊~~~原來是Backscatter Protection

jtain 發表於 2008-1-18 15:40:19

不好意思「Backscatter Protection」在哪裡啊！
很久沒有去設定參數了...:L

jtain 發表於 2008-1-18 15:50:43

啊！找到了。
果然是這個問題，這是否意味著對方的 mail server 軟體太舊，所以會錯誤的解釋相關的訊息

「就是這樣！喵！」...我本來就想跟你說應該是對方的伺服器太舊...但不好意思說...<IMG alt="" src="http://www.suma.tw/forum/images/smilies/default/tongue.gif" border=0 smilieid="7">
