Unable to Process Incoming Emails on Aliyun Mail

Description

I believe it is the SEARCH command in the IMAP protocol with the specified CHARSET parameter that caused the issue. The server completely rejects the CHARSET parameter, resulting in a malfunction.

We can choose to modify the existing code or switch to the v2 version of go-imap, which should resolve the issue. This is because the comments in v2 specifically mention this situation. https://github.com/emersion/go-imap/blob/3e14ef3cd2b7de584d2f27881d8e017e4f794802/imapclient/search.go#L36-L44

Gitea Version

1.22.3

Can you reproduce the bug on the Gitea demo site?
