postfix是/etc/postfix/sasl/passwd文件的所有者如果有人有任何建議，我將不勝感激！！！
我得到了一些幫助，他們發現 passwd 文件沒有像 main.cf 文件在 smtp.gmail.com 周圍那樣的括號，所以我改變了它並用 postmap 重新映射，然後它給了我一個不同的錯誤，提到不值得機制可用，所以我進行了Google搜尋，發現其他人也有同樣的錯誤，並且剛剛安裝了 cyrus-sasl-plain 並且成功了。感謝所有的幫助。
檢查您的格式
/etc/postfix/sasl/passwd是否正確。它應該顯示為：
smtp.gmail.com user@gmail.com:password_or_app_password設置此文件後，您需要在其上執行
postmap，以更新雜湊。postmap /etc/postfix/sasl/passwd然後重新載入後綴。
systemctl reload postfix
