翻译成英文：如果我们以含非英文EAI地址发送邮件给一个传统邮件系统会怎么样呢？结果多数是失败或者弹回。但现实世界里大多数的邮件系统并未升级到支持EAI难道使用了EAI就变成了信息孤岛无法和其他系统通讯了吗？下面是我们提出的解决方案：1 给所有使用EAI地址的用户分配一个传统的ASCII邮件地址别名2 当收件方系统不支持EAI的时候我们回退到使用这个ASCII邮箱别名来与对方通讯这个过程是在服务器端

What would happen if we send an email with a non-English EAI address to a traditional email system? The majority of the time, it would result in failure or bounce back. However, in the real world, most email systems have not upgraded to support EAI. Does this mean that using EAI would isolate us and prevent communication with other systems? Here is the solution we propose:

1. Assign a traditional ASCII email address alias to all users using EAI addresses.
2. When the recipient's system does not support EAI, we fallback to using this ASCII email alias to communicate with them. This process is automatically done on the server side by modifying the sender's address and email headers
