[請益] Exchange Spam問題

[et54987 (象)]

小弟不才

最近在弄雙域名郵件

現在已經測試到

內部兩個網域名稱的Mail都可以寄出到Gmail 內部郵件互寄也OK

不過從外部回信卻會出現550 M.5 User Unknown

請問問題可能是出在哪邊呢??

推 epenpal:完整貼出退信比較好抓。spam 是啟用exchange上的功能嗎?
SPAM是桓基的硬體式

→ ddoll288:要看spam gateway的log,才知道user unknown原因
→ ddoll288:可以直接問桓基
推 epenpal:桓基的產品不熟、不過spam通常要跟ad整合去排除非ad的user
→ epenpal:應該是這段有問題
→ epenpal:應該是說 排除不存在於後端exchange的mail address
我是智障...
樓上幾位簡單幾語 讓我發現我忘記在SPAM上面新增[e-mail]的員工信箱
難怪被退 囧

推 Aries322:信送進來了,但是被 Mail Gateway 退了,unknow user 表示
→ Aries322:你的 Mail Gateway 不認識該 SMTP Record 的使用者
→ Aries322:原因應該是你的 Mail Gateway 沒有做 SMTP Route
→ Aries322:將該網域 b.com.tw 新增一筆 SMTP Route 到 Mail Server
→ Aries322:應該這樣就收的到了
是的!~
謝謝您精闢的解說XDD
