我已經用谷歌搜尋了這個錯誤，但我讀過/嘗試過的任何東西都不起作用 - 任何人都知道它是什麼

答案1
smtpd_sasl_path正如你所看到的，我們的輸出中沒有postconf -n
為什麼？答案很簡單。因為沒有smtpd_sasl_path設定。看看你的第一個片段：其中有一個拼字錯誤。你寫了smptd_sasl_path = 私有/身份驗證——但是sm之間是有差別的TPd 和 sm點d.
由於 Postfix 沒有關於在哪裡找到套接字的信息，Postfix 聲稱「連接失敗」。
修復它，它就會起作用。 :-)
最後：下次請記住：postconf -n仔細閱讀並確保 Postfix 具有與您認為 Postfix 應該具有的相同的信息，這始終是查找故障的重要步驟。
答案2
有相同的錯誤，不同的問題。
必須編輯/etc/dovecot/conf.d/10-master.conf並取消註釋unix_listener並新增user和group行。
service auth {
unix_listener /var/spool/postfix/private/auth {
mode = 0660
user = postfix
group = postfix
}
