Postfix Dovecot 的 SMTP 身份驗證問題
我買了一個域名
example.com
和一個 VPS,我用 iRedMail 設置了一個郵件伺服器。不想讓 iRedMail 搞亂我的 Nginx,我決定自己安裝 Nginx 和 Roundcube。但是,它說 SMTP 伺服器不支持身份驗證。SMTP 沒問題。

編輯:在一些問題之後,我啟用了:
postconf | grep smtp_sasl_auth_enable smtp_sasl_auth_enable = yes
但是使用 openssl s_client,我得到了:
503 5.5.1 Error: authentication not enabled
更新:
設置後
smtpd_sasl_auth_enable = yes
我有機會輸入我的密碼,但它說密碼錯誤。我正在使用密碼管理器,所以密碼應該是正確的。此外,我可以使用憑據通過 imap 登錄。535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6
編輯:在 /var/log/maillog 上,我看到了這個致命的:通過 `smtp_sasl_password_maps’ 配置參數指定密碼表所以我使用了 postconf | grep smtp_sasl_password_maps smtp_sasl_password_maps = 也許這就是問題所在。但它不應該是空的,因為我使用了 iredmail,所以它應該是什麼?
最後,我設法設置了我的服務。如果你想設置你的,這裡有幾點你應該注意。
啟用 smtp_sasl_auth_enable 和 smtpd_sasl_auth_enable。我不知道為什麼預設情況下不啟用它。設置 smtp_sasl_password_maps ,所以它知道在哪裡可以找到密碼。在 roundcube 上,設置 tls:// 前綴,如果使用自簽名證書,則在 smtp 選項中設置
