Amavis：無法使用模組 IO::Socket::IP 連接到套接字 127.0.0.1:*：連接被拒絕
嘗試調試郵件伺服器，現在我收到此錯誤，我認為這應該是伺服器無法正常工作的原因：

在 Postfix 的 main.cf 中，您有以下行：
content_filter = amavis:[127.0.0.1]:10024不是錯誤，只是我用來練習避免混淆的一個旁注：使用唯一標識符，例如：
content_filter = amavisfeed:[127.0.0.1]:10024主要問題在於你的postfix的master.cf。您基本上是在告訴 Postfix 在 main.conf 中使用 amavisd，但 Postfix 需要知道如何在 master.cf 中使用 amavisd。
例如，您可以將以下內容放在“127.0.0.1:10025 inet n - - - - smtpd”部分之前：amavisfeed unix - - n - 2 lmtp -o lmtp_data_done_timeout=1200 -o lmtp_send_xforward_command=yes儘管存在這些因素，您仍應檢查 amavisd 及其使用的組件（例如 ClamAV、SpamAssassin）的配置是否正確，尤其是在使用者和套接字方面，並且 amavisd 允許對其使用的組件使用套接字通過 tmpfiles.d 中的條目。
