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?? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.230.136.141

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 Delivery to the following recipient failed permanently: et54987@b.com.tw Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain b.com.tw by mail.b.com.tw.

要看spam gateway的log,才知道user unknown原因
12/28 00:44, 2F

12/28 00:44, , 3F
可以直接問桓基
12/28 00:44, 3F

12/28 00:56, , 4F
桓基的產品不熟、不過spam通常要跟ad整合去排除非ad的user

12/28 00:56, , 5F
應該是這段有問題
12/28 00:56, 5F

12/28 00:59, , 6F
應該是說 排除不存在於後端exchange的mail address
12/28 00:59, 6F
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et54987@b.com.tw的員工信箱 難怪被退 囧 ※ 編輯: et54987 來自: 61.230.198.71 (12/28 01:32)

信送進來了,但是被 Mail Gateway 退了,unknow user 表示
12/28 23:18, 7F

12/28 23:19, , 8F
你的 Mail Gateway 不認識該 SMTP Record 的使用者
12/28 23:19, 8F

12/28 23:19, , 9F
原因應該是你的 Mail Gateway 沒有做 SMTP Route
12/28 23:19, 9F

12/28 23:20, , 10F
將該網域 b.com.tw 新增一筆 SMTP Route 到 Mail Server

12/28 23:20, , 11F
應該這樣就收的到了
12/28 23:20, 11F
是的!~ 謝謝您精闢的解說XDD ※ 編輯: et54987 來自: 61.230.204.191 (12/29 13:02)
