Email Send
发送邮件，支持 SMTP 和 Resend API 两种方式。
🚀 快速使用
# 发送简单邮件
python3 scripts/send_email.py \

--subject "Meeting Tomorrow" \
--body "Hi, let's meet at 2pm tomorrow."
# 发送 HTML 邮件
python3 scripts/send_email.py \
--to [email protected] \
--subject "Weekly Report" \
--body "<h1>Report</h1><p>Here are the updates...</p>" \
--html
# 发送带附件的邮件
python3 scripts/send_email.py \

# 指定使用 Resend
python3 scripts/send_email.py \

--subject "Test" \
--body "Hello" \
--provider resend
⚙️ 配置
在 ~/.smtp_config 中配置（二选一或两个都配）：
方式 1: Resend API（推荐，更简单）
{
"resend_api_key": "re_xxxxx",
"resend_from": "[email protected]"
}
获取 API key: https://resend.com
注意：免费账户只能发给注册邮箱，要发给其他人需要验证域名。
方式 2: SMTP（163/QQ/Gmail 等）
{
"host": "smtp.163.com",
"port": 465,
"user": "[email protected]",
"password": "your-auth-code",
"from": "[email protected]",
"use_ssl": true
}
两个都配（自动 fallback）
{
"resend_api_key": "re_xxxxx",
"resend_from": "[email protected]",
"host": "smtp.163.com",
"port": 465,
"user": "[email protected]",
"password": "your-auth-code",
"from": "[email protected]",
"use_ssl": true
}
配置完后设置权限：
chmod 600 ~/.smtp_config
📋 参数
| 参数 | 必填 | 说明 |
|---|---|---|
--to |
✅ | 收件人邮箱 |
--subject |
✅ | 邮件标题 |
--body |
✅ | 邮件内容 |
--html |
❌ | 以 HTML 格式发送 |
--attachments |
❌ | 附件路径，多个用逗号分隔 |
--provider |
❌ | auto/smtp/resend（默认 auto） |
🔄 Provider 选择逻辑
auto（默认）：优先 Resend，失败则 fallback 到 SMTPsmtp：强制使用 SMTPresend：强制使用 Resend API
📧 常见 SMTP 配置
| 邮箱 | Host | Port | SSL |
|---|---|---|---|
| 163 | smtp.163.com | 465 | true |
| smtp.qq.com | 465 | true | |
| Gmail | smtp.gmail.com | 587 | false |
| Outlook | smtp.office365.com | 587 | false |
注意：163/QQ/Gmail 都需要使用授权码而非登录密码。
🔐 安全
- 凭据存储在
~/.smtp_config，权限应设为 600 - API key 和密码不会出现在命令行参数中
- 配置文件不应提交到版本控制
🐛 常见问题
认证失败：检查授权码是否正确，是否开启了 SMTP 服务
Resend 403：免费账户只能发给注册邮箱，需要验证域名才能发给其他人
连接超时：检查网络，或者端口是否被防火墙拦截
