How to earn unlimited points in QQ mailbox

I don't know what the points are used for now, but anyway, as long as you set them up, you can use them permanently. If you like to use them, go and use them! To explain, QQ mailboxes have points as long as they receive emails or send emails every day. In this way, you can subscribe to QQ mails. For example, if there are 10 columns, you will receive 10 emails every day. Then set the automatic reply/automatic forwarding (Settings - General), fill in the content and email address as you like, and then you can automatically send emails every day. That's it. Even if you don't log in, you can permanently earn QQ mailbox points.
