Hello, I want the QQ mailbox to automatically pop up a notice when it receives an email. How should I set it? I tried to set it in the system settings, but it didn't work.

You can set it directly in QQ settings. As long as there is new mail, the desktop will automatically pop up to remind you that there is new mail. In QQ settings, there is a basic setting-information display-reminder-new email reminder. Check it. As long as there is a new email, it will pop up automatically like a QQ message. I hope this helps you.
