I can't find the spam inbox.

Hello, if you just click Add to White List, then this letter can't be found. You have to click to retrieve it first, because this letter was intercepted by the system and hasn't reached your mailbox yet. Then, in order not to be blocked in the future, you need to click Add to White List. If you also click Search, you can check the storage location of the letter in the same location, showing the intercepted place. If it doesn't work, search it. I hope it will help.
