+# NewSzxcn Email
+
+NewSzxcn Email is a self-hosted mail server with a complete Webmail client and administration console. It bundles Go, React, Postfix, Dovecot, Rspamd, and SQLite into an all-in-one Docker deployment.
+
+[Releases](https://github.com/zxyszx/NewSzxcn-Email/releases) · [Chinese README](README.md)
+
+## Features
+
+- Webmail with compose, drafts, attachments, search, labels, folders, reminders, import, and export
+- Multiple domains and mailboxes, DKIM, DNS checks, verified forwarding, and external IMAP
+- Incoming mail rules with conditions, ordering, forwarding, moving, and bulk application
+- Administration for users, permission quotas, domains, mailboxes, messages, and send queues
+- SMTP, IMAP, POP3, Postfix, Dovecot, Rspamd, and SMTP Submission
+- Release checks, admin-only web updates, pre-update database backups, and CLI rollback
+
+## One-command install
+
+Debian and Ubuntu on `amd64` or `arm64` are supported.
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/zxyszx/NewSzxcn-Email/main/install.sh | sudo bash
+```
+
+The installer configures `/opt/newszxcn-email`, starts the Docker services, and waits for the health check. DNS records and provider port restrictions must still be configured by the operator.
+
+During first installation it prompts for the firewall policy, mail hostname, administrator username/password, and Web mode. Automatic mode configures host Nginx and obtains a Let's Encrypt certificate with the official `acme.sh` client. The default username is `admin`; an empty password generates 12 characters, while a custom password requires at least 6 characters.
+
+## Update
+
+System administrators can click the version badge in the admin sidebar to review and install a GitHub release. The updater is only reachable on the internal Docker network.
+
+CLI update and rollback:
+
+```bash
+sudo newszxcn-email update
+sudo newszxcn-email rollback
+```
+
+Useful commands:
+
+```bash
+sudo newszxcn-email status
+sudo newszxcn-email logs
+sudo newszxcn-email restart
+sudo newszxcn-email certificate
+sudo newszxcn-email uninstall
+```
+
+The uninstall command removes the containers and generated Nginx configuration while preserving certificates, configuration, messages, and the database under `/opt/newszxcn-email`.
+
+## Required ports
+
+Open TCP ports `25`, `80`, `443`, `465`, `587`, `993`, and `995` as needed. Public delivery also requires correct MX, SPF, DKIM, and DMARC records.
+
+## Manual source deployment
+
+```bash
+git clone https://github.com/zxyszx/NewSzxcn-Email.git
+cd NewSzxcn-Email/deploy
+cp .env.example .env
+docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build

+
+容器停止后菜单会显示“已停止”；配置存在但运行文件残缺时会显示“安装不完整”并默认选择修复。空白服务器进入安装后，会依次引导配置防火墙、邮件服务器域名、邮箱地址域名、管理员邮箱和 Web 部署方式。选择重新安装会先将
+`/opt/newszxcn-email` 完整改名备份，失败时自动恢复原目录、Nginx 和旧容器。更新前会
+校验数据库备份并保存镜像、Compose、环境、安装脚本和 Nginx，失败时执行完整恢复。
+
+脚本会自动完成：
+
+- 安装或检查 Docker Engine 与 Docker Compose v2
+- 选择自动添加邮局必要端口规则，或保留现有防火墙由用户自行配置
+- 自动检测并确认邮箱地址域名；创建管理员邮箱时可选择默认 `admin` 前缀或自行输入前缀，例如服务器域名 `mail.example.com`、前缀 `admin` 会创建 `admin@example.com`；回车自动生成 12 位密码，自定义密码最少 6 位
+- 选择自动 Nginx + SSL、宝塔/已有 Nginx 反代或 HTTP 测试模式
+- 自动模式使用官方 `acme.sh` 签发和续期证书，不会强制停止占用 80 端口的进程
+- 创建 `/opt/newszxcn-email` 持久化目录
+- 拉取 GHCR 镜像并启动邮件服务
+- 生成后台在线更新所需的内部鉴权令牌
+- 等待 Web 与 API 健康检查通过
+
+安装完成后访问配置的 `LANQIN_PUBLIC_BASE_URL`。首次登录后，在后台添加邮件域名并按照 DNS 检测页配置记录。
+
+> 一键安装不会替你修改 DNS，也不能绕过云厂商对 25 端口的限制。公网收信前必须确认 25 端口可入站，公网发信前需确认 25 端口可出站。
+
+## 更新与回滚
+
+### 后台页面更新
+
+超级管理员可点击后台侧栏中的版本号，查看当前版本、最新版本与更新日志。点击“立即更新”后，系统会先在线备份 SQLite 数据库，再拉取新镜像并重启；页面会等待服务恢复后自动刷新。
+
+更新期间容器会短暂重启。接口会先向页面确认更新已受理，再异步替换容器；页面遇到临时 `502/503/504` 或网络中断时会继续检查服务状态，不会立即误报更新失败。
+
+更新服务只在 Docker 内部网络开放，不映射公网端口。普通用户和普通后台权限组无法执行系统更新。
+
+### 命令行更新
+
+```bash
+sudo newszxcn-email update
+```
+
+命令行更新会创建完整回滚快照、校验数据库备份并执行健康检查。需要恢复上次更新前的镜像、数据库和配置时运行：
+
+```bash
+sudo newszxcn-email rollback
+```
+
+手动回滚会先要求确认，并额外备份当前数据库，再恢复更新前版本。回滚后的镜像会保持锁定，直到下一次明确执行更新。
+
+常用运维命令：
+
+```bash
+sudo ns
+sudo newszxcn-email guide
+sudo newszxcn-email credentials
+sudo newszxcn-email reset-password
+sudo newszxcn-email repair
+sudo newszxcn-email status
+sudo newszxcn-email logs
+sudo newszxcn-email restart
+sudo newszxcn-email certificate
+sudo newszxcn-email uninstall
+```
+
+`credentials` 显示安装或最近一次命令行重置时记录的管理员登录信息。数据库中的密码采用 bcrypt 哈希，无法反向查看；如果管理员后来在网页修改过密码，记录值可能已经失效。`reset-password` 只重置配置管理员的统一登录密码，并同步该管理员名下邮箱的 SMTP/IMAP 密码，不会修改普通用户或其邮箱。重置前会先备份并校验数据库。
+
+`uninstall` 会移除容器和自动生成的 Nginx 配置，但不删除 `/opt/newszxcn-email` 中的配置、证书、数据库与邮件。卸载时可以单独停止当前域名的 acme.sh 自动续期，不会影响 acme.sh 管理的其他域名。
+
+## DNS 与端口
+
+至少需要以下 DNS 记录：
+
+| 类型 | 示例 | 用途 |
+| --- | --- | --- |
+| A / AAAA | `mail.example.com -> 服务器 IP` | 邮件主机与 Webmail |
+| MX | `example.com -> mail.example.com` | 接收邮件 |
+| SPF TXT | 后台生成 | 声明允许发信的服务器 |
+| DKIM TXT | 后台按域名生成 | 邮件签名验证 |
+| DMARC TXT | 后台生成建议值 | 发信策略与报告 |
+
+服务器防火墙和云安全组应按需开放：
+
+| 端口 | 协议 | 用途 |
+| --- | --- | --- |
+| 25 | TCP | SMTP 服务器间收发信 |
+| 80 / 443 | TCP | Webmail 与证书签发 |
+| 465 / 587 | TCP | 邮件客户端 SMTP 发信 |
+| 993 | TCP | IMAP SSL |
+| 995 | TCP | POP3 SSL |
+
+## 数据目录
+
+默认部署目录为 `/opt/newszxcn-email`：
+
+```text
+/opt/newszxcn-email/
+|-- .env                 # 环境配置与内部更新令牌
+|-- docker-compose.yml   # 邮箱主服务与内部更新服务
+|-- data/                # SQLite、附件和更新前备份
+|-- mail/                # Maildir 邮件原文
+|-- dkim/                # DKIM 私钥
+`-- certs/               # Web、SMTP、IMAP、POP3 共用的 TLS 证书
+```
+
+升级和重建容器不会删除这些目录。备份时应同时保存 `data`、`mail`、`dkim`、`certs` 与 `.env`。
+
+## 手动部署
+
+需要自行控制 Compose 配置时：
+
+```bash
+git clone https://github.com/zxyszx/NewSzxcn-Email.git
+cd NewSzxcn-Email/deploy
+cp .env.example .env
+# 编辑 .env
+docker compose pull
+docker compose up -d
+```
+
+本地源码构建：
+
+```bash
+cd deploy
+docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
+```
+
+更完整的证书、外部 SMTP、Webhook 和排错说明见 [deploy/README.md](deploy/README.md)。

+## 技术栈
+
+- 后端：Go、Chi、SQLite
+- 前端：React、TypeScript、TanStack Query、shadcn/ui、Tailwind CSS
+- 邮件：Postfix、Dovecot、Rspamd
+- 部署：Docker、Docker Compose、GitHub Actions、GHCR
+
+## 本地开发
 
 ```bash
 cd apps/api
-go mod download
-go test ./...
 go run ./cmd/server
 ```
 
-Frontend (new terminal):
-
 ```bash
 cd apps/web
-corepack enable
-corepack prepare pnpm@10.28.2 --activate
 pnpm install
 pnpm run dev
 ```
 
-Open:
-
-- Web: `http://localhost:5173`
-- API: `http://localhost:8080`
-
-The default admin email is `admin@lanqin.local`. For development, explicitly set `LANQIN_ADMIN_PASSWORD`; if it is not set, the backend generates a random password on first startup and prints it to the logs.
-
-### Docker Deployment (single container)
-
-A server only needs the Compose files and configuration under `deploy/`; building from source is not required:
+提交前建议运行：
 
 ```bash
-cd deploy
-cp .env.example .env
-# Edit .env: domain, public URL, admin email, admin password, etc.
-docker compose pull
-docker compose up -d
+cd apps/api && go test ./...
+cd apps/web && pnpm run check
 ```
 
-Common commands:
+## 开源协议
 
-```bash
-# View logs
-docker compose logs -f lanqin-email
-
-# Pull the latest image and restart
-docker compose pull
-docker compose up -d
-
-# Stop services
-docker compose down
-```
-
-To build the image locally from the full source repository:
-
-```bash
-cd deploy
-cp .env.example .env
-docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
-```
-
-See [`deploy/README.md`](./deploy/README.md) for more deployment details.
-
-## First Deployment Checklist
-
-1. Edit `deploy/.env`: at minimum, change `LANQIN_PUBLIC_HOSTNAME`, `LANQIN_PUBLIC_BASE_URL`, `LANQIN_ADMIN_EMAIL`, and `LANQIN_ADMIN_PASSWORD`.
-2. In production, mount real TLS certificates and set `LANQIN_TLS_CERT_FILE` / `LANQIN_TLS_KEY_FILE`.
-3. Log in to the admin panel and add your mail domain.
-4. Copy and configure MX, SPF, DKIM, and DMARC records from domain management, then run the DNS check.
-5. Create mailbox accounts, alias forwarding, or permission groups; enable registration, 2FA, Turnstile, and self-service mailbox requests as needed.
-6. Use the admin SMTP test and Webmail send/receive tests to confirm the full path works.
-

-
-Mail flow:
-
-1. **Receiving**: Postfix receives mail → Rspamd scores/marks it → Dovecot writes to Maildir → API worker syncs it into SQLite → Webmail displays it.
-2. **Sending**: Webmail calls the API → API builds MIME → SMTP submits to Postfix or an external SMTP server → mail is delivered to the destination.
-3. **Local delivery**: In development, internal mailboxes can send directly into the recipient Inbox; if `LANQIN_SMTP_HOST` is not configured, external recipients are not actually delivered.
-4. **Third-party clients**: Connect with SMTP 465/587, IMAP 993, or POP3 995; in production, configure certificates that match `LANQIN_PUBLIC_HOSTNAME`.
-5. **External mailbox access**: Users can add external IMAP accounts in personal mailbox management. Local-storage mode syncs mail into the database; remote-direct mode reads from the remote server each time and does not write into local mail tables.
-
-## Development and Verification
-
-```bash
-# API tests
-cd apps/api
-go test ./...
-
-# Web checks and build
-cd apps/web
-pnpm run check
-
-# Single-container source build verification
-cd deploy
-docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
-```
-
-## Production Notes
-
-- In production, always change the default admin password and protect `.env`, the SQLite database, Maildir, and DKIM private keys.
-- The Web UI can sit behind host Nginx / aaPanel / an edge gateway, but SMTP/IMAP/POP3 certificates must be mounted separately for Postfix/Dovecot inside the container.
-- Cloud providers often block port 25 by default; if public email does not send or receive, first check ports, security groups, firewalls, and reverse DNS.
-- SQLite is suitable for single-node deployments; before multi-node deployment, migrate the database and adjust Postfix/Dovecot query configuration accordingly.
-
-## SMTP Submission
-
-- Third-party client SMTP submission on `465/587` is handled by the LanQin API process.
-- Before enabling SMTP submission, configure `LANQIN_TLS_CERT_FILE` / `LANQIN_TLS_KEY_FILE`; the API will not expose 465/587 externally with a localhost self-signed certificate.
-- Postfix only keeps port `25` for public inbound mail and internal/external relay.
-- Webmail/API and third-party client sends are first written into Sent, then enter the send queue.
-- The send queue is relayed by a LanQin API background worker to `LANQIN_SMTP_HOST:LANQIN_SMTP_PORT`; failures are audited and retried with backoff.
-- v1 supports sending from the user's own mailbox. For send-as, use an enabled alias forwarding source that points to the user's mailbox, or configure `send_as_grants` in the database.
-- If the client later writes its own Sent copy through IMAP APPEND, Maildir sync deduplicates by `Message-ID` within the Sent folder.

-├── apps/api              # Go API、SQLite schema、邮件同步与业务逻辑
-├── apps/web              # React/Vite Webmail 与管理后台
-├── deploy                # Docker Compose、镜像构建、Postfix/Dovecot/Rspamd 配置
-└── .github/workflows     # Docker 镜像发布流水线
+支持 Debian / Ubuntu 的 `amd64` 与 `arm64` 服务器。建议至少 2 核、2 GB 内存，并准备一个已解析到服务器的邮件主机名，例如 `mail.example.com`。
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/zxyszx/NewSzxcn-Email/main/install.sh | sudo bash
 ```
 
-## 环境要求
+已使用 `root` 登录时，也可以使用：
 
-### 开发环境
+```bash
+bash <(curl -fsSL https://raw.githubusercontent.com/zxyszx/NewSzxcn-Email/main/install.sh)
+```
 
-- Go 1.25+
-- Node.js 20+
-- pnpm 10.28.2（可通过 corepack 启用）
+脚本会自动完成：
 
-### 部署环境
+- 安装或检查 Docker Engine 与 Docker Compose v2
+- 选择自动添加邮局必要端口规则，或保留现有防火墙由用户自行配置；不会清空已有防火墙规则
+- 分开确认邮件服务器域名和邮箱地址域名，创建唯一管理员邮箱；默认 `admin@邮箱地址域名`，回车自动生成 12 位密码，自定义密码最少 6 位
+- 选择自动 Nginx + SSL、宝塔/已有 Nginx 反代或 HTTP 测试模式
+- 自动模式使用官方 `acme.sh` 签发和续期证书，不会强制停止占用 80 端口的进程
+- 创建 `/opt/newszxcn-email` 持久化目录
+- 拉取 GHCR 镜像并启动邮件服务
+- 生成后台在线更新所需的内部鉴权令牌
+- 等待 Web 与 API 健康检查通过
 
-- Docker Engine
-- Docker Compose v2
-- 可解析的邮件域名，以及可用的 25 / 465 / 587 / 993 / 995 等端口
+安装完成后访问配置的 `LANQIN_PUBLIC_BASE_URL`。首次登录后，在后台添加邮件域名并按照 DNS 检测页配置记录。
 
-> 公网收发邮件还需要正确配置 MX、SPF、DKIM、DMARC，并确认云厂商未封禁 SMTP 端口。
+> 一键安装不会替你修改 DNS，也不能绕过云厂商对 25 端口的限制。公网收信前必须确认 25 端口可入站，公网发信前需确认 25 端口可出站。
 
-## 快速开始
+## 更新与回滚
 
-### 本地开发
+### 后台页面更新
 
-后端：
+超级管理员可点击后台侧栏中的版本号，查看当前版本、最新版本与更新日志。点击“立即更新”后，系统会先在线备份 SQLite 数据库，再拉取新镜像并重启；页面会等待服务恢复后自动刷新。
+
+更新服务只在 Docker 内部网络开放，不映射公网端口。普通用户和普通后台权限组无法执行系统更新。
+
+### 命令行更新
+
+```bash
+sudo newszxcn-email update
+```
+
+命令行更新会保留当前镜像、备份数据库并执行健康检查。需要回滚时运行：
+
+```bash
+sudo newszxcn-email rollback
+```
+
+常用运维命令：
+
+```bash
+sudo newszxcn-email status
+sudo newszxcn-email logs
+sudo newszxcn-email restart
+sudo newszxcn-email certificate
+sudo newszxcn-email uninstall
+```
+
+`uninstall` 会移除容器和自动生成的 Nginx 配置，但不删除 `/opt/newszxcn-email` 中的配置、证书、数据库与邮件。
+
+## DNS 与端口
+
+至少需要以下 DNS 记录：
+
+| 类型 | 示例 | 用途 |
+| --- | --- | --- |
+| A / AAAA | `mail.example.com -> 服务器 IP` | 邮件主机与 Webmail |
+| MX | `example.com -> mail.example.com` | 接收邮件 |
+| SPF TXT | 后台生成 | 声明允许发信的服务器 |
+| DKIM TXT | 后台按域名生成 | 邮件签名验证 |
+| DMARC TXT | 后台生成建议值 | 发信策略与报告 |
+
+服务器防火墙和云安全组应按需开放：
+
+| 端口 | 协议 | 用途 |
+| --- | --- | --- |
+| 25 | TCP | SMTP 服务器间收发信 |
+| 80 / 443 | TCP | Webmail 与证书签发 |
+| 465 / 587 | TCP | 邮件客户端 SMTP 发信 |
+| 993 | TCP | IMAP SSL |
+| 995 | TCP | POP3 SSL |
+
+## 数据目录
+
+默认部署目录为 `/opt/newszxcn-email`：
+
+```text
+/opt/newszxcn-email/
+├── .env                 # 环境配置与内部更新令牌
+├── docker-compose.yml   # 邮箱主服务与内部更新服务
+├── data/                # SQLite、附件和更新前备份
+├── mail/                # Maildir 邮件原文
+├── dkim/                # DKIM 私钥
+└── certs/               # Web、SMTP、IMAP、POP3 共用的 TLS 证书
+```
+
+升级和重建容器不会删除这些目录。备份时应同时保存 `data`、`mail`、`dkim`、`certs` 与 `.env`。
+
+## 手动部署
+
+需要自行控制 Compose 配置时：
+
+```bash
+git clone https://github.com/zxyszx/NewSzxcn-Email.git
+cd NewSzxcn-Email/deploy
+cp .env.example .env
+# 编辑 .env
+docker compose pull
+docker compose up -d
+```
+
+本地源码构建：
+
+```bash
+cd deploy
+docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
+```
+
+更完整的证书、外部 SMTP、Webhook 和排错说明见 [deploy/README.md](deploy/README.md)。
+
+## 技术栈
+
+- 后端：Go、Chi、SQLite
+- 前端：React、TypeScript、TanStack Query、shadcn/ui、Tailwind CSS
+- 邮件：Postfix、Dovecot、Rspamd
+- 部署：Docker、Docker Compose、GitHub Actions、GHCR
+
+## 本地开发
 
 ```bash
 cd apps/api
-go mod download
-go test ./...
 go run ./cmd/server
 ```
 
-前端（新终端）：
-
 ```bash
 cd apps/web
-corepack enable
-corepack prepare pnpm@10.28.2 --activate
 pnpm install
 pnpm run dev
 ```
 
-访问：
-
-- Web：`http://localhost:5173`
-- API：`http://localhost:8080`
-
-默认管理员邮箱为 `admin@lanqin.local`。建议开发时显式设置 `LANQIN_ADMIN_PASSWORD`；如果未设置，后端首次启动会随机生成密码并输出到日志。
-
-### Docker 部署（单容器）
-
-服务器只需要 `deploy/` 下的 Compose 文件和配置，不需要源码构建：
+提交前建议运行：
 
 ```bash
-cd deploy
-cp .env.example .env
-# 修改 .env：域名、访问地址、管理员邮箱、管理员密码等
-docker compose pull
-docker compose up -d
+cd apps/api && go test ./...
+cd apps/web && pnpm run build
 ```
 
-常用命令：
-
-```bash
-# 查看日志
-docker compose logs -f lanqin-email
-
-# 更新镜像并重启
-docker compose pull
-docker compose up -d
-
-# 停止服务
-docker compose down
-```
-
-如需在完整源码仓库中本地构建镜像：
-
-```bash
-cd deploy
-cp .env.example .env
-docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
-```
-
-更多部署细节见 [`deploy/README.md`](./deploy/README.md)。
-
-## 首次部署清单
-
-1. 编辑 `deploy/.env`：至少修改 `LANQIN_PUBLIC_HOSTNAME`、`LANQIN_PUBLIC_BASE_URL`、`LANQIN_ADMIN_EMAIL`、`LANQIN_ADMIN_PASSWORD`。
-2. 生产环境建议挂载真实 TLS 证书，并设置 `LANQIN_TLS_CERT_FILE` / `LANQIN_TLS_KEY_FILE`。
-3. 登录管理后台，添加邮件域名。
-4. 在域名管理中复制并配置 MX、SPF、DKIM、DMARC 记录，然后点击 DNS 检测。
-5. 创建邮箱账号、别名转发或权限组，按需开启注册、2FA、Turnstile、自助申请邮箱。
-6. 使用后台 SMTP 测试与 Webmail 收发测试确认链路正常。
-

-邮件流转：
-
-1. **收件**：Postfix 接收邮件 → Rspamd 评分/标记 → Dovecot 写入 Maildir → API worker 同步到 SQLite → Webmail 展示。
-2. **发件**：Webmail 调用 API → API 构造 MIME → SMTP 提交给 Postfix 或外部 SMTP → 投递到目标地址。
-3. **本地投递**：开发环境中，系统内邮箱互发可直接写入对方 Inbox；未配置 `LANQIN_SMTP_HOST` 时不会真正投递外部收件人。
-4. **第三方客户端**：可通过 SMTP 465/587、IMAP 993、POP3 995 连接；生产环境请配置匹配 `LANQIN_PUBLIC_HOSTNAME` 的证书。
-5. **外部邮箱接入**：个人邮箱管理可添加外部 IMAP 账号。本地存储模式会同步入库；远端直连模式每次读取远端，不写入本地邮件表。
-
-## 开发与验证
-
-```bash
-# API 测试
-cd apps/api
-go test ./...
-
-# Web 检查与构建
-cd apps/web
-pnpm run check
-
-# 单容器源码构建验证
-cd deploy
-docker compose -f docker-compose.yml -f docker-compose.build.yml up -d --build
-```
-
-## 生产注意事项
-
-- 生产环境必须修改默认管理员密码，并妥善保管 `.env`、SQLite 数据库、Maildir 与 DKIM 私钥。
-- Web 可放在宿主机 Nginx/宝塔/边缘网关后，但 SMTP/IMAP/POP3 证书需要单独挂载给容器内 Postfix/Dovecot。
-- 云厂商常默认封禁 25 端口；无法收发公网邮件时先检查端口、安全组、防火墙与反向 DNS。
-- SQLite 适合单机部署；多节点部署前需要迁移数据库，并同步调整 Postfix/Dovecot 查询配置。
-
-## SMTP 提交
-
-- 第三方客户端的 SMTP 提交 `465/587` 由 LanQin API 进程处理。
-- 启用 SMTP 提交前必须配置 `LANQIN_TLS_CERT_FILE` / `LANQIN_TLS_KEY_FILE`；API 不会用 localhost 自签证书对外提供 465/587。
-- Postfix 只保留 `25` 端口，用于公网入站邮件和内部/外部 relay。
-- Webmail/API 和第三方客户端发信都会先写入 Sent，再进入发送队列。
-- 发送队列由 LanQin API 后台 worker relay 到 `LANQIN_SMTP_HOST:LANQIN_SMTP_PORT`，失败会记录审计并按退避策略重试。
-- v1 支持本人邮箱发信；如需 send-as，可使用启用的别名转发 source 指向本人邮箱，或在数据库中配置 `send_as_grants`。
-- 如果客户端随后又通过 IMAP APPEND 写入自己的 Sent 副本，Maildir 同步会按 Sent 文件夹内的 `Message-ID` 去重。

-# LanQin Email Docker 部署说明

+## 一键安装与更新
+
+推荐直接使用仓库根目录的管理脚本：
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/zxyszx/NewSzxcn-Email/main/install.sh | sudo bash
+```
+
+后续操作：
+
+```bash
+sudo newszxcn-email update
+sudo newszxcn-email status
+sudo newszxcn-email logs
+sudo newszxcn-email rollback
+sudo newszxcn-email guide
+sudo newszxcn-email credentials
+sudo newszxcn-email reset-password
+sudo newszxcn-email reset-2fa
+```
+
+一键安装会把配置和数据放在 `/opt/newszxcn-email`，并部署内部 Watchtower 更新服务。该服务不映射公网端口，仅接受带随机令牌的容器内请求；后台“立即更新”也只允许超级管理员执行。
+
+首次安装会依次询问防火墙模式和邮件服务器域名，自动检测邮箱地址域名，再选择默认 `admin` 前缀或自行创建管理员邮箱前缀，最后输入密码并选择 Web 部署方式。防火墙可以选择自动添加邮局必要端口规则或保留现有规则，不会清空服务器已有防火墙。自动 Web 模式会把容器绑定到 `127.0.0.1:8088`，配置宿主机 Nginx，并使用官方 `acme.sh` 申请和续期证书。例如服务器域名 `mail.newszxcn.com`、选择默认前缀会创建 `admin@newszxcn.com`；自定义管理员密码最少 6 位，留空则生成 12 位密码。
+
+安装后输入 `ns` 可以打开统一管理菜单。更新前会创建包含数据库、镜像、Compose、环境、安装脚本和 Nginx 的回滚快照；更新或健康检查失败时会自动恢复。手动完整回滚前还会单独备份当前数据库，回滚镜像会保持锁定到下一次更新。
+
+菜单可查看安装或最近一次命令行重置时记录的管理员登录信息，也可单独重置唯一管理员的统一登录密码。密码采用 bcrypt 哈希，无法从数据库反向解密；网页修改密码后，脚本中的记录可能已经失效。命令行重置前会备份并校验数据库，同时同步该管理员名下邮箱的 SMTP/IMAP 密码，不会修改普通用户或其邮箱。唯一管理员 2FA 锁死时可使用 `sudo newszxcn-email reset-2fa` 应急关闭。

+## Telegram 通知
+
+### 私聊新邮件通知
+
+每台邮局可以在“管理后台 -> 系统设置 -> 通知”中独立配置 Telegram 私聊邮件通知：
+
+1. 使用 `@BotFather` 创建机器人并填写 Bot Token。
+2. 在 Telegram 中打开该机器人并发送 `/start`。
+3. 回到后台点击“自动获取”，系统会填写最近一个私聊 Chat ID。
+4. 选择“正文摘要”或“尽量显示完整正文”，点击“测试通知”。
+5. 测试成功后开启“私聊新邮件通知”并保存。
+
+Bot Token 不会通过设置查询接口返回。新邮件通知会先持久化到 SQLite 队列，Telegram 暂时不可用时按退避策略重试；通知失败不会阻塞收件。通知包含发件人、收件邮箱、主题、收件时间、正文和附件名称，不会把附件文件上传到 Telegram。
+
+手动部署也可以在 `.env` 中设置 `LANQIN_TELEGRAM_MAIL_ENABLED`、`LANQIN_TELEGRAM_BOT_TOKEN`、`LANQIN_TELEGRAM_PRIVATE_CHAT_ID` 和 `LANQIN_TELEGRAM_BODY_MODE`。后台保存的值会持久化到数据库，并在后续启动时优先使用。
+
+### GitHub Release 版本频道通知
+
+版本频道通知由 GitHub Release 工作流统一发送，与各台已部署邮局是否更新无关。仓库需要配置以下 GitHub Actions Secrets：
+
+```text
+TELEGRAM_RELEASE_BOT_TOKEN
+TELEGRAM_RELEASE_CHAT_ID
+```
+
+`TELEGRAM_RELEASE_CHAT_ID` 可以填写频道用户名（例如 `@YourChannel`）或频道数字 ID。机器人必须先添加为频道管理员，并具有发布消息权限。工作流只在检查、全部 Docker 镜像和 GitHub Release 成功后发送一次；未配置密钥时自动跳过，Telegram 发送失败也不会把版本发布标记为失败。
+
 ## 邮件服务边界
 
 - Postfix 读取 `/data/lanqin.db` 中的 `domains`、`mailboxes`、`aliases`。
 - Dovecot 读取同一个 SQLite 数据库进行邮箱认证，并使用 `/var/mail/vhosts` 作为 Maildir 根目录。
 - 第三方客户端可使用 IMAP SSL `993`、POP3 SSL `995`、SMTP SSL `465` 或 Submission `587`。
 - Rspamd 通过 milter 接入 Postfix，负责 DKIM 签名和垃圾邮件标记。
-- Rspamd 会周期性从 SQLite 导出域名 DKIM 私钥到容器内 `/var/lib/rspamd/dkim`。
+- Rspamd 会周期性从 SQLite 导出域名 DKIM 私钥到容器内 `/var/lib/rspamd/dkim`；仅当密钥内容变化时重新载入签名配置，避免继续使用内存中的旧密钥。
 - Go API 是 Webmail 和管理后台入口；浏览器不直接连接 SMTP/IMAP/POP3。
 - Go API 会读取 `LANQIN_MAILDIR_ROOT=/var/mail/vhosts`，周期扫描 Maildir，把 Postfix/Dovecot 入站邮件同步成 Webmail 索引。
 - 第三方客户端可通过 LanQin API 提供的 SMTP `465/587` 发信；Webmail/API 和第三方客户端的“已发送”都由 API 写入，外发投递进入发送队列并由 API worker relay/retry，客户端后续 IMAP APPEND 到 Sent 会按 `Message-ID` 去重。

 ## 邮件客户端 TLS 证书
 
 Web 站点可以由宿主机 Nginx / 宝塔反代到容器 `80`，但 SMTP/IMAP/POP3 端口不会使用 Web 反代的证书。
+此时可在 `.env` 调整 Web 端口绑定，避免与宿主机 Nginx 的 `80/443` 冲突：

+```dotenv
+LANQIN_HTTP_BIND=127.0.0.1:8088
+```

 如果第三方客户端连接 `993/995` 时提示证书是 `localhost`，说明 Dovecot 仍在使用容器自带的测试证书。LanQin API 的 SMTP `465/587` submission 不会使用自签测试证书；启用前必须配置可读的真实证书。
