版本：Debian 11 5.10.92-1 x86_64 - nginx/1.21.6 - mysql 15.1 10.5.12-MariaDB - PHP 7.4.25 (cli) - dovecot-core/stable，现在 1:2.3.13+dfsg1-2
我的 postfix/dovecot 配置已正常工作，可以接收电子邮件。从 rainloop 切换到 roundcube 后，我在 roundcube web 中看不到任何收件箱电子邮件。但偶尔我会登录 roundcube，并在收件箱中看到我的所有电子邮件，但如果我单击任何内容或刷新页面，它们都会消失。从 roundcube 发送电子邮件也只会导致无休止的加载轮，没有超时。
不幸的是 roundcube 没有错误日志，而 dovecot 只有成功登录日志。除了消失的电子邮件外，没有任何迹象表明出现了问题。

/var/log/roundcube/error.log是空的。
我非常确定这是 dovecot 上的 IMAP 的问题，因为登录可以，但电子邮件检索只有 10% 的时间有效。没有任何错误日志可供故障排除，我不知道接下来该怎么办，只能反复尝试弄乱配置文件。
有人可以帮忙吗？
。
我排除了很多配置，因为它们太庞大了。我可以添加任何其他配置文件，但我认为这些是最相关的。
Roundcube配置：
<?php
$config = array();
// Do not set db_dsnw here, use dpkg-reconfigure roundcube-core to configure database!
include_once("/etc/roundcube/debian-db-roundcube.php");
$config['default_host'] = 'localhost';
$config['smtp_server'] = 'localhost';
// SMTP port. Use 25 for cleartext, 465 for Implicit TLS, or 587 for STARTTLS (default)
$config['smtp_port'] = 587;
// SMTP username (if required) if you use %u as the username Roundcube
// will use the current username for login
$config['smtp_user'] = '%u';
// SMTP password (if required) if you use %p as the password Roundcube
// will use the current user's password for login
$config['smtp_pass'] = '%p';
// provide an URL where a user can get support for this Roundcube installation
// PLEASE DO NOT LINK TO THE ROUNDCUBE.NET WEBSITE HERE!
$config['support_url'] = '';
// Name your service. This is displayed on the login screen and in the window title
$config['product_name'] = 'Roundcube Webmail';
// This key is used to encrypt the users imap password which is stored
// in the session record. For the default cipher method it must be
// exactly 24 characters long.
$config['des_key'] = 'k';
// List of active plugins (in plugins/ directory)
// Debian: install roundcube-plugins first to have any
$config['plugins'] = array(
);
// skin name: folder from skins/
$config['skin'] = 'elastic';
// Disable spellchecking
// Debian: spellchecking needs additional packages to be installed, or calling external APIs
// see defaults.inc.php for additional informations
$config['enable_spellcheck'] = false;
