我已经处理了超过 12 个小时的问题圆立方体在我的 VPS Ubuntu 16.04 中安装。IMAP 服务器 (dovecot) 和 SMTP 服务器正在运行，并且telnet没有出现连接被拒绝错误。

问题

但是，当我转到我的网络邮件并尝试使用用户名root和相关的 SSH/SFTP 密码登录时（为了测试它是否正常工作，然后我将创建其他电子邮件地址），它返回以下错误：

IMAP Error in /usr/share/nginx/roundcubemail/program/lib/Roundcube/rcube_imap.php (193): Login failed for root from 190.20.86.0. AUTHENTICATE PLAIN: * BYE. Internal error ocurred. Refer to server log for more information

日志

和/var/log/nginx/mail.log是/var/log/nginx/roundcube.error空的

配置

$config['debug_level'] = 4; //to debug the php authentication failed error

我该如何在尝试登录时解决这个问题？我非常担心在这 24 小时的停机时间内我丢失了多少电子邮件（20+）。

谢谢你的回答。Kevin Nathan Andrews

答案1

root 无法使用 postfix 接收邮件，dovecot 无法通过 IMAP 发送邮件。使用 Unix 用户进行身份验证并不是一个好主意，而且有很多方法可以使用 postfix 和 dovecot 设置虚拟邮件。

如果您确实需要测试，请创建一个非特权用户，这应该可以工作。
