關於[X-Return-Path]

jtain

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: SpamMail@instant.com.tw

X-Return-Path: prvs=1901a27026=SpamMail@instant.com.tw

jtain

這是我收到信得檔頭部份：

對方收到的寄件人就是： prvs=1901a27026=SpamMail@instant.com.tw
所以被系統認為有不合法的字元，故應該是拉圾信.....

----------------------------------
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

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
