安装完成

Zmail System 已就绪。

  • 管理员账号：
  • 已添加邮箱：
⚠️ 重要：请立即删除 install.php
否则他人可以重新运行安装程序，覆盖你的数据库。

接下来建议：

!$c['ok'] && empty($c['warn'])); $can_proceed = empty($blocked); ?> 安装向导 - 第 <?= $step ?> 步 - Zmail System

📬 Zmail System 安装向导

第 1 步：环境检测

✅ 所有必需项均已通过
❌ 有 项未通过，请先解决

第 2 步：创建数据库

系统将在 data/ 目录下创建：

SQLite 是文件型数据库，不需要额外申请，适合虚拟主机。

第 3 步：创建管理员账号

至少 3 个字符
建议包含大小写字母和数字

第 4 步：添加第一个邮箱

这一步可以跳过，安装完成后再添加。

[ 'label' => 'Gmail', 'host' => '{imap.gmail.com:993/imap/ssl}INBOX', 'tip' => '需在 Google 账户生成「应用专用密码」。', ], 'qq' => [ 'label' => 'QQ 邮箱', 'host' => '{imap.qq.com:993/imap/ssl}INBOX', 'tip' => '开启 IMAP 服务后获得 16 位授权码，用户名填 QQ 号。', ], 'outlook' => [ 'label' => 'Outlook', 'host' => '{outlook.office365.com:993/imap/ssl}INBOX', 'tip' => '需使用应用密码；部分账户默认关闭 IMAP。', ], '163' => [ 'label' => '163 邮箱', 'host' => '{imap.163.com:993/imap/ssl}INBOX', 'tip' => '开启 IMAP 后生成授权码。', ], 'custom' => [ 'label' => '自定义', 'host' => '', 'tip' => '格式：{imap.服务器:993/imap/ssl}INBOX', ], ]; ?>

第 5 步：确认安装

✅ 所有配置已完成
点击下方按钮后，系统会生成安装锁文件，install.php 将无法再次访问。
