郵件伺服器是否出問題才導致她沒收到信？
系統環境如下：1. 作業系統：2003 Standard Server2. 是否安防毒軟體：Symantec Antivirus
3. 是否安裝防火牆：Netscreen 10gt Firewall 4. 自行架設 DNS
5. 使用ADSL 固接制（固定 IP）
6. 是否使用 IP 分享器或路由器：防火牆內建NAT
7. MDaemon、AntiVirus 版本 ：MDaemon PRO v9.6.6，並沒有使用它的AntiVirus
----------------------------------------------------------------------------------------------------------------------------------------------------------------下方是 2008-11-04 的spam(in) log有一位使用者 [email protected] 告訴我：由於她沒有收到E-MAIL導致會議遲到。老闆要追究相關責任，並且要我提出郵件伺服器是否出問題才導致她沒收到信。 此封信有許多的收信者，大家都有收到，唯獨她沒有！所以我想請教大家，以下應該是一個完整的收件流程，沒錯吧！如果沒錯的話，沒有收到信件應該是她自己的電腦問題，不應該扯到我這來吧！ 以下有幾點疑問（紅色標示處），還請各位先進給小弟指點迷津，謝謝！！（因為字數超過，所以分成二部份。還請版大見諒！）---------------------------------------------------------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------------------------------------------

<P>這是內部寄給內寄的信吧？感覺好像出去外面繞了一圈才進來。</P>
<P> </P>
<P>看起來信是收到了...但說不定被她的電腦中的防毒或防駭軟體給擋了？或者進了她的垃圾郵件資料夾？</P> 是的，該封信件是由內部的另一位使用者 [email protected]
寄給一堆內部的使用者。(由內部寄給內部)
只是！我不懂！樓主何出此言？---->感覺好像是出去繞了一圈才進來。
樓主是從哪裏看出了些端倪？

<P>從上面這段猜的。</P>

<P>如果沒有繞出去，理論上內部寄的信應該會是內部的 IP。除非你們內部員工每個人使用的都是實體 IP，並且公司沒有前端的防牆或路由器。</P>
