Bai Hua's settlement certificate says that the mailbox has been sent out, but it just can't be received.

Maybe there is something wrong with your email settings, or you can check with the other party whether the email has been sent.

Open the setting interface of your mailbox, click the receiving rule, and check whether the conditions of the filtering rule are set improperly, which may be that the settlement voucher is directly deleted.

Second, check whether there is the other party's email address in your blacklist. If so, delete it from the blacklist and you can receive it.

Secondly, check whether there is a settlement voucher in your spam box, because it is likely to be misjudged by the anti-spam system, so just add the other party to the white list.

If your email address is set normally, the other party will definitely send you a reconciliation certificate. You can try to change another email address. It may be that the server is broken. See if the other party has written back, or you can contact the customer service center in the mailbox to solve it.
