aliyun: 企业邮箱发件配置 - 代码/程序/python/smtp/pop3

添加账号

这里假设你已经有了一个企业账户(目前可以免费申请)

打开链接 https://qiye.aliyun.com/alimail/auth/login

添加用户: cc-notify@js.work

打开设置

这个设置，不太好找，可以参考链接中找到截图

• 添加应用密码(类似于 qq 邮箱的 token 之类的)
• https://qiye.aliyun.com/alimail/entries/v5.1/setting/account-security
• 设置 → 账户与安全 → 账户安全 → 三方客户端登录安全管理 → 生成新密码
