[IDN Mail]Gmail says:550 relay not permitted

A few weeks ago, I created an idn e-mail in the panel, which looks like: EnglishLetters@IDN TLD. After testing, gmail and hotmail can write to it and receive letters successfully. But after reinstalling the panel recently, gmail and hotmail can no longer send mail to EnglishLetters@IDN TLD, gmail prompt: The following is the response from the remote server:
550 relay not permitted
Panel version: 1.16.10 and 1.16.11
OS: Ubuntu 18.04, 20.04, 22.04
How to fix this problem please?

Check /var/log/exim4/mainlog

when i use gmail sent a mail to my idn mail, the log was:

Thanks.

Yes, I got your mail at my idn mailbox.

However, if you use [email protected] or [email protected], it cannot be successfully sent to my idn email.

The current situation is: gmail/hotmail cannot send letters to my xxx@idn tld, but can send letters to my English email address, for example: [email protected].
