我無法從我的郵件服務器發送電子郵件。我已經嘗試了我遇到的每種可能的解決方案。首先，我能夠發送電子郵件，但他們要的垃圾郵件，所以我決定安裝OpenDKIM，並添加了KEY到DNS記錄。希望它能解決問題，但NO。Gmail阻止來自我的郵件服務器（Postfix）的電子郵件CentOS 6

你的問題是一個很好的，但它更關係到系統管理不是編程。因此，它是Stack Overflow的[off-topic]（http://stackoverflow.com/help/on-topic），並且更適合[ServerFault]（http://serverfault.com/）。 –
O_O啊。你說得對，它與編程無關。這是我第一次訪問ServerFault社區，因爲您向我提供了鏈接。我會在那裏發佈。謝謝sooo Anthony Geoghega！ – ryspbsk
