Aliyun mail uses UidSearch() or Search() method reporting "invalid command or parameters"

[xuecangqiuye]

I'm using v2 version.
I saw the same problem at #412, but it seems that it doesn't have a solution for this problem.
Can you tell that if this problem is caused by Aliyun mail server or by my mistaken usage?

Can you obtain debug logs?

Hm. That command looks correct to me. I'm not sure why the server refuses it.

So it may be a server problem.
Thanks a lot!

It was indeed a server issue.
I found some relevant information to help anyone who encounters the same situation in the future.
