我已經安裝了 elastix 3 穩定版本（postfix、cyrus sasl2）。我在本地網路中用作電子郵件伺服器。這裡一切工作如下：
- 從本地發送電子郵件到本地 =好的！
- 從本地端向外部發送電子郵件=好的！
- 接收電子郵件（從本地發送的）=好的！
- 接收電子郵件（即傳送從外部）=不！ ***
事實上，唯一的問題是我無法在收件匣中收到從外部發送的電子郵件，但是我已經可以在收件匣中收到從本地網路發送的郵件。恐怕是出了什麼問題。但如果有人能在這個問題上幫助我，我將不勝感激。 master.cf和main.cf檔案也如下，我不知道是否應該進行任何其他設定。另請注意看來我的 ISP 封鎖了 25，所以我使用另一個連接埠作為 smtp。

答案1
我找到了答案。事實上，問題不在於郵件伺服器。好像是25埠 應該是開放的為了接收來自外部的郵件。沒有這個，它不起作用。我已經在其他論壇上看到過一些關於它的內容，但我無法表達它的重要性。解封後，外部郵件收到良好。我只是想分享我的解決方案和我得到的答案。 :)
