+# Roundcube
+
+## 产品介绍
+Roundcube 是一个开源 Webmail 客户端，可通过浏览器连接已有的 IMAP/SMTP 邮件服务器收发邮件。
+
+## 主要功能
+- 通过浏览器访问 IMAP 邮箱
+- 使用外部 SMTP 服务器发送邮件
+- 支持内置插件、主题和自定义配置
+- 使用本地 SQLite 保存 Webmail 元数据
+
+## 访问说明
+安装后通过 `http://<服务器 IP>:18090` 访问，实际端口以安装表单中的 `PANEL_APP_PORT_HTTP` 为准。
+
+## Introduction
+Roundcube is an open source Webmail client for accessing an existing IMAP and SMTP mail server from a browser.
+
+## Features
+- Browser-based IMAP mail access
+- Send mail through an external SMTP server
+- Built-in plugins, themes and custom configuration support
+- Local SQLite metadata storage
+
+## 部署说明
+- 本应用使用官方 Docker 镜像 `roundcube/roundcubemail:1.7.1-apache-nonroot`。
+- 应用分类：邮件服务。
+- 支持架构：amd64、arm64。
+- Roundcube 只是 Webmail 客户端，不包含邮件服务器。请先准备可用的 IMAP/SMTP 服务，例如已有邮箱服务或应用商店中的 Maddy Mail Server。
+
+## 端口
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| PANEL_APP_PORT_HTTP | Web 访问端口 | 18090 | 是 |
+
+## 数据持久化
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| APP_DATA_DIR | SQLite 数据库、自定义配置和 Enigma 插件数据目录 | ./data | 是 |
+
+升级或迁移前，请先在 1Panel 中备份上述数据目录。
+
+## 参数说明
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| ROUNDCUBEMAIL_DEFAULT_HOST | IMAP 主机，可使用 `tls://` 或 `ssl://` 前缀 | ssl://mail.example.com | 是 |
+| ROUNDCUBEMAIL_DEFAULT_PORT | IMAP 端口 | 993 | 是 |
+| ROUNDCUBEMAIL_SMTP_SERVER | SMTP 主机，可使用 `tls://` 或 `ssl://` 前缀 | tls://mail.example.com | 是 |
+| ROUNDCUBEMAIL_SMTP_PORT | SMTP 端口 | 587 | 是 |
+| ROUNDCUBEMAIL_USERNAME_DOMAIN | 登录用户名自动补全域名，留空表示不补全 | 空 | 否 |

+| ROUNDCUBEMAIL_DES_KEY | Roundcube 加密密钥，安装后不要随意修改 | 随机生成 | 是 |
+
+## 使用说明
+- 如果 IMAP/SMTP 使用隐式 TLS，主机通常写成 `ssl://mail.example.com`，端口使用 `993` 或 `465`。
+- 如果 IMAP/SMTP 使用 STARTTLS，主机通常写成 `tls://mail.example.com`，端口使用 `143` 或 `587`。
+- `ROUNDCUBEMAIL_DES_KEY` 会影响 Roundcube 保存的加密数据，迁移或重建容器时应保持不变。
+- 自定义 Roundcube 配置可放入数据目录的 `config` 子目录，文件名需以 `.php` 结尾。
