Postfix
後綴收件人地址被拒絕：刪除 permit_mynetworks 後訪問被拒絕錯誤
我有一個郵件伺服器，如果濫用，它必須從 Postfix 配置文件（main.cf）中刪除“permit_mynetworks”。我只將它設置為允許 SASL autheniented 中繼。但是現在，postfix 會拒絕任何外國收件人。有人可以告訴我有什麼問題嗎？提前致謝！
以下是配置：

我建議您至少允許該特定守護程序的環回 IP 地址 127.0.0.1。這樣做不會造成太大的風險。
此外，由於您在與 postfix 相同的伺服器上執行 amavis，因此您可以改用 linux 套接字來優化事物。
