我從 18.04LTS 升級到 19.10。但是，帶有 SASL (cyrus) 的 postfix 已停止工作。使用廣泛描述的正常方法將其配置為 smtp.office365.com:587 的智慧型主機/中繼。
如果沒有偵錯設定，日誌中會出現常見的「無效參數」錯誤：
Nov 17 00:15:21 ianb-pc postfix/smtp[2277]: 939A25A20DB: SASL authentication failed; cannot authenticate to server smtp.office365.com[52.97.133.242]: invalid parameter supplied
Nov 17 00:15:21 ianb-pc postfix/smtp[2278]: AB6735A0D5A: to=<ianb@removed>, relay=smtp.office365.com[40.100.174.194]:587, delay=214662, delays=214661/0.02/0.46/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server smtp.office365.com[40.100.174.194]: invalid parameter supplied)
經過一些調試後，下面是級別 4 的 mail.log 的一部分。
有任何想法嗎？謝謝你的幫忙。伊恩
